make a comparison and write down ways in which plant cells are different from animal cells

Plant and animal cells are both eukaryotic, but they differ in several clear structural and functional ways.

Quick Scoop

Imagine two small “cities”: one is a green, walled city that makes its own food (plant cell), and the other is a flexible city that must import food (animal cell). Below is a comparison showing how these two cell “cities” differ.

Main differences in a nutshell

  • Plant cells have a rigid cell wall made of cellulose outside the cell membrane; animal cells have only a cell membrane.
  • Plant cells contain chloroplasts for photosynthesis; animal cells never have chloroplasts.
  • Plant cells usually have one large central vacuole; animal cells have small, many vacuoles or sometimes none visible.
  • Animal cells have centrioles and centrosomes for cell division; these are typically absent in higher plant cells.
  • Lysosomes are clearly developed in animal cells; in plants, their role is mostly taken over by the vacuole.
  • Plant cells are often larger and more regular/rectangular; animal cells are usually smaller and more irregular in shape.

Functional differences (what they do)

How they get and use energy

  • Plant cells are autotrophic: chloroplasts use light energy to make sugars by photosynthesis, then mitochondria break down that sugar for energy.
  • Animal cells are heterotrophic: they must take in food, then mitochondria break it down during cellular respiration.

Storage and support

  • The large central vacuole in plant cells stores water, ions, and some wastes, and also presses against the cell wall, helping the plant keep upright (turgor).
  • Animal cells use smaller vacuoles and vesicles for storage and rely more on skeleton and other tissues for body support, not on cell turgor.

A simple way to remember

  • Plant cell = “green, walled factory”: has a wall, chloroplasts, and a big central vacuole so it can make its own food and stay stiff.
  • Animal cell = “soft, flexible eater”: no wall or chloroplasts, has centrioles and lysosomes, and must find food from outside.

If you’re ever unsure, look for a cell wall and chloroplasts in a diagram: if they’re there, you’re almost certainly looking at a plant cell.

TL;DR: Plant cells have a cell wall, chloroplasts, and a big central vacuole and are usually boxy and autotrophic, while animal cells lack those structures, are more flexible in shape, and depend on external food.
