What is the difference between animal cells and plants cell? ?

There are several key differences between animal cells and plant cells:

1. Cell Wall: Plant cells have a rigid cell wall made of cellulose, which provides structural support and protection for the cell. Animal cells do not have a cell wall.

2. Chloroplasts: Plant cells contain chloroplasts, which are organelles that carry out photosynthesis and produce energy for the cell. Animal cells do not have chloroplasts.

3. Vacuoles: Plant cells have a large central vacuole that stores water, nutrients, and waste products. Animal cells have smaller vacuoles or none at all.

4. Shape: Plant cells are typically rectangular or square in shape, while animal cells are more irregular in shape.

5. Organelles: Both animal and plant cells have many of the same organelles, such as the nucleus, mitochondria, and endoplasmic reticulum. However, plant cells also have unique organelles like chloroplasts and a large central vacuole.

Overall, while animal and plant cells share many similarities, there are also several key differences that reflect their different functions and structures.

Animal Cells vs. Plant Cells

| Feature | Animal Cells | Plant Cells |
|---|---|---|
| Cell Shape | Irregular, no rigid cell wall | Fixed, rigid cell wall made of cellulose |
| Cell Division | Cytokinesis by pinching | Cytokinesis by cell plate formation |
| Centrioles | Present | Absent |
| Vacuoles | Small, numerous | Large, central vacuole |
| Chloroplasts | Absent | Present |
| Cell Surface | Plasma membrane | Cell wall (primary and secondary) |
| Cytoplasm | Fills the cell | Trapped in the cell wall, creating a central vacuole |
| Nucleus | Single, not membrane-bound | Single, surrounded by a nuclear membrane |
| Ribosomes | Free and attached to the endoplasmic reticulum (ER) | Free and attached to the ER and chloroplasts |
| Mitochondria | Present | Present |
| Endoplasmic Reticulum | Rough and smooth | Rough, smooth, and endoplasmic reticulum |
| Golgi Apparatus | Present | Present |
| Lysosomes | Present | Absent |
| Peroxisome | Present | Absent |
| Glyoxysome | Absent | Present |
| Storage | Food stored in small vacuoles | Food stored in large, central vacuole |
| Mobility | Motile (some) | Immobile |
| Heterotrophs | Obtain energy from eating other organisms | Autotrophs |
| Examples | Humans, lions, dogs | Trees, flowers, algae |
