MAKE IT SIMPLE AND FOR 9TH GRADE

Answer 1

- Cytoplasm
- Jelly-like fluid that fills the cell and holds the organelles.
- Many chemical reactions happen here and it helps move materials around.
- Analogy: the room where cell activities take place.

- Chloroplasts
- Found in plant cells and some algae.
- Carry out photosynthesis: use sunlight to make food (glucose) and oxygen from water and CO2.
- Contain the green pigment chlorophyll.
- Analogy: solar panels or a kitchen that makes food from sunlight.

- Cell wall
- A rigid outer layer outside the cell membrane in plants, fungi and many bacteria.
- Gives the cell shape, support and protection; prevents the cell from bursting.
- In plants it is mainly made of cellulose.
- Analogy: a brick wall or fence around a house.

- Centrioles
- Small tube-like structures found in most animal cells (not in most plant cells).
- Help organize spindle fibers that pull chromosomes apart during cell division (mitosis and meiosis).
- Sometimes help form cilia and flagella.
- Analogy: organizers or cranes that guide chromosome movement during cell division.
