Animals dont have chlorolplasts because one we are not plants and two we have evolved in a way that we never needed to perform photosynthisis our cells make enough ATP with the mitocondria already.

∙ 13y agoCell walls are used by plant cells for the rigidity necessary for the plant to be self-supporting while it grows upright. Animal cells are soft and flexible and the skeleton, muscles, and other animal tissues support them. Animals are not photosynthetic organisms, so chloroplasts are not needed in their cells for the photosynthesis that takes place in plant cells.

Wiki User
∙ 14y agoThey are used for photosynthesis so the plant can make food for itself, and animals gain nutrition by eating it instead.
Wiki User
∙ 11y agoBecause it is an animal cell. an animal cell does not need chlorophyll, cell wall and chloroplast as they are not autotropds.
Wiki User
∙ 11y agoChloroplasts conduct photosynthesis therefor an animal cell does not need it.
Wiki User
∙ 8y agoAnimals not having cell wall. They do not need chloroplasts because of they are not doing photosynthesis.
Wiki User
∙ 7y agoChloroplasts convert light energy of the Sun into sugars that can be used by the plant's cells. Animal cells don't use photosynthesis, so have no chloroplast cells.

What 2 plant cells don't have chloroplasts?
onion cells dont contain chloroplasts as they are underground so cant photosynthesise
Which structures in the leaf are responsible for photosynthesis?
there are lots of things that people dont understand and i dont aswell
What is the chloroplast and why dont cells have chloroplast?
Only photosynthetic organisms (organisms that perform photosynthesis), such as plants, some bacteria, and some protistans, have chloroplasts. Animal cells do not have chloroplasts because they do not carry out photosynthesis.
Why onion cells do not contain chloroplast?
Because an onion develops in the ground, and chloroplasts develop in the sunlight. Therefore no chloroplasts form. Think of it this way: Tree leaves contain chloroplasts because they contain chlorophyll in order for the leaves to turn colors. But who has ever heard of an onion changing colors because it's fall?! Onions dont need chloroplasts, so they dont have them.
What organelles that animal cells have but plant cells dont?
nucleolus, centrosome and that's all i know! :-D
Do phloem cells contain chloroplasts?
no they dont
What 2 plant cells don't have chloroplasts?
onion cells dont contain chloroplasts as they are underground so cant photosynthesise
A plant cell has two parts that animal cells do not have they are the?
These parts are the cell wall (animal cells just have a cell membrane) and the vacuole. Plants also have chloroplasts which animal cells do not have.
Which structures in the leaf are responsible for photosynthesis?
there are lots of things that people dont understand and i dont aswell
What organelles do plants have that animals do not?
Lysosome ,Centriole, and VesicleActually, animal cells do not have any different organelles than plant cells, other than plant cells having a membrane. animal cells do not have a membrane, they have a cell wall.
Why do plant cells have chloroplasts and a rigid cell wall and animals cells dont?
The chloroplasts make the plant stem green.
What is the difference in root hair cells and leaf cells?
root hair cells dont have chloroplasts
Are plastids found in animal cells?
A plastid is a major organelle found in the cells of plants and algae. There are no plastids, however, found in animal cells.
What do you call leaves that only contain chlorophyll in some of their cells?
im not sure, all i noe is that it is a special form of variegation xx
Is there a difference between animal and plant white blood cells?
plants dont have white blood cells...they have chloroplasts
What is the chloroplast and why dont cells have chloroplast?
Only photosynthetic organisms (organisms that perform photosynthesis), such as plants, some bacteria, and some protistans, have chloroplasts. Animal cells do not have chloroplasts because they do not carry out photosynthesis.
Why do you see chloroplasts in the Elodea cell but not the onion cell?
Because an onion develops in the ground, and chloroplasts develop in the sunlight. Therefore no chloroplasts form. Think of it this way: Tree leaves contain chloroplasts because they contain chlorophyll in order for the leaves to turn colors. But who has ever heard of an onion changing colors because it's fall?! Onions dont needchloroplasts, so they dont have them.
