Below is a list of the major differences: ANIMAL CELLS PLANT CELLS Does not have a cell wall, irregular in shape Has a cell wall, regular in shape No chloroplast present Chloroplast present Small temporary vacuoles or no vacuole Large vacuoles located in the centre of the cell Starch grains not present Starch grains present The nucleus is usually located centrally Due to the central location of the vacuole, the nucleus of the cell may be located at the edge of the cell TYPICAL ANIMAL CELL Similarities between plant and animal cells: -Both have a cell surface membrane that surrounds the cell
When a plant has been in the sun for some hours, the starch granules can get quite big as the glucose produced in photosynthesis is converted into starch. Have you ever wondered why green plants are all slightly different colours ? Well there is more than one kind of chlorophyll, and there are other photosynthetic pigments
Chloroplasts take the light energy given off by the sun and convert it into sugars, which are used by the cells to help the plant stay healthy and grow
During this process, electrons are shuttled through an iron-containing cytochrome enzyme system along membranes of the cristae which result in the phosphorylation of ADP (adenosine diphosphate) to form ATP (adenosine triphosphate). In fact, chloroplast DNA, including the protein-coding RBCL gene, is often used at the family level to show the relationships between genera and species within plant families
A COMPARISON OF MITOCHONDRIA IN PLANT AND ANIMAL CELLS
Plant mitochondria react to the janus green test and stain with supravital dyes in substantially the same way as animal mitochondria, though it is certainly more difficult to obtain a good coloration. In addition to this, similar and parallel variations occur in their arrangement in the several tissues and even in the individual cells of plants and animals
Cells and Organelles
They are both surrounded by two bilayer membranes suggesting one membrane originated from the plasma membrane of the cell and one from the plasma membrane of the hypothetical invader. This is the endoplasmic reticulum (ER for short) and its central space or lumen is a continuation of the lumen between the membranes of the nuclear envelope
It contains enzymes and produces and digests lipids (fats) and membrane proteins; smooth ER buds off from rough ER, moving the newly-made proteins and lipids to the Golgi body and membranes stroma - part of the chloroplasts in plant cells, located within the inner membrane of chloroplasts, between the grana. Rough ER transport materials through the cell and produces proteins in sacks called cisternae (which are sent to the Golgi body, or inserted into the cell membrane)

Just like our postal packages, which should have a correct shipping address, the proteins produced in the ER should be correctly sent to their respective address. Taking a look inside a cell Have you ever wondered what the inside of a cell looks like? If you think about the rooms in our homes, the inside of any animal or plant cell has many similar room-like structures called organelles
Biology for Kids: Plant Cell Chloroplasts
Other Functions Other functions of chloroplasts include fighting off diseases as part of the cell's immune system, storing energy for the cell, and making amino acids for the cell
In both plant and animal cells, mitochondria, the cell's "powerhouses," convert energy in nutrients into useable energy through the process of aerobic respiration. Chloroplasts are the structures that give leaves their green color and, more importantly, allow plants to acquire their energy from the Sun rather than from food, which is the primary source of energy for animals

Inserting Chloroplasts into Animal Cells
Assuming I'm right in thinking that heart tissue beats independantly of any nerves, it should be theoretically possible for a heart to exist alone if provided with energy. As for the problem about some of the chloroplast's DNA being nuclear, I think the best solution would be to use the least evolved plant still alive today
Although chloroplasts look like mitochondria at first glance, mitochondria actually work in the opposite direction as they are responsible in breaking down the nutrients and sugars that the cell receives and convert that into energy. The stromal lamellae, responsible in connecting the stacks of sacs, acts like the skeleton of the chloroplast and keeps all of the sacs at a safe distance from each other; and maximizing the efficiency of the organelle

Their main function is as a space-filler in the cell, but they can also fill digestive functions similar to lysosomes (which are also present in plant cells). The inner membrane encloses an area called the stoma, which is analogous to the matrix in mitochondria and houses DNA, RNA, ribosomes, and different enzymes

Plant cells vs. Animal cells - Biology Online
A plant cell is bounded by a cell wall and the living portion of the cell is within the walls and is divided into two portions: the nucleus, or central control center; and the cytoplasm, a fluid in which membrane bound organelles are found. The proteins synthesized on ribosomes bound to granular endoplasmic reticulum are transferred from the lumen (open space inside endoplasmic reticulum) to the golgi apparatus for secretion outside the cell or distribution to other organelles

Plant and animal cells are both eukaryotic cells, so they have several features in common, such as the presence of a cell membrane, and cell organelles, like the nucleus, mitochondria and endoplasmic reticulum. Cellular respiration occurs in mitochondria on animal cells, which are structurally somewhat analogous to chloroplasts, and also perform the function of producing energy

Their main function is as a space-filler in the cell, but they can also fill digestive functions similar to lysosomes (which are also present in plant cells). The inner membrane encloses an area called the stoma, which is analogous to the matrix in mitochondria and houses DNA, RNA, ribosomes, and different enzymes
Their DNA is circular, as it is in the prokaryotes, and their ribosomes and reproductive methods (binary fission) are more like those of the prokaryotes. In higher plants, lamellae, internal membranes with stacks (each termed a granum) of closed hollow disks called thylakoids, are also usually dispersed throughout the stroma
All green plant take part in the process of photosynthesis which converts energy into sugars and the byproduct of the process is oxygen that all animals breathe. The chloroplasts with the nucleus and cell membrane and ER are the key organelles of pathogen defense.The most important function of chloroplast is to make food by the process of photosynthesis
Chloroplast Function in Plant Cell Structure
In the light reaction stage, sunlight is converted to chemical energy in the form of ATP (free energy containing molecule) and NADPH (high energy electron carrying molecule). The sugar can be stored in the form of starch, used during respiration, or used in the production of cellulose.Plant Cell: Structures and OrganellesTo learn more about organelles that can be found in typical plant cells, see: Cell (Plasma) Membrane - a thin, semi-permeable membrane that surrounds the cytoplasm of a cell, enclosing its contents

(Mitochondrial genomes are even smaller than the genomes of chloroplasts.) Coding sequences for the majority of chloroplast proteins have been lost, so these proteins are now encoded by the nuclear genome, synthesized in the cytoplasm, and transported from the cytoplasm into the chloroplast. Plant cells have high concentrations of molecules dissolved in their cytoplasm, which causes water to come into the cell under normal conditions and makes the cell's central vacuole swell and press against the cell wall
Biology4Kids.com: Cell Structure: Chloroplasts
When the energy from the Sun hits a chloroplast and the chlorophyll molecules, light energy is converted into the chemical energy found in compounds such as ATP and NADPH. The lamellae act like the skeleton of the chloroplast, keeping all of the sacs a safe distance from each other and maximizing the efficiency of the organelle
