Cells Flashcards
Jill placed an animal cell and a plant cell in water, and water started entering the cells the animal cell burst while the plant cell did not. Explain why the plant cell did not burst.
The plant cell has a cell wall to prevent it from bursting and give structural support but the animal cell does not have a cell wall.
Explain why an animal cell can not make food
It does not have chloroplasts which contain chlorophyll, so they cannot trap light to make food.
Some agar-agar was prepared in a petri dish. A fingernail scratched the agar. Over 2 weeks, brown patches appeared on the agar-agar and increased in the 2 weeks.
Explain why that happens.
The bacteria in our fingernails were transferred to the agar-agar in the process of scratching it. It then went through cell division and increased in number, causing the brown patches to increase over time.
How do leaf cells make its own food?
Leaf cells have chloroplasts which contain chlorophyll that traps light for photosynthesis to make its own food.
Some cells were taken from different parts of a chicken and were observed under a microscope. It was realized that the cells had different shapes and structures. It was believed that it is because some cells did not have a cell wall.
Explain why this is false.
Explain why the cells had different shapes and structures
The cells from chicken are animal cells which do not have cell walls, thus chicken cells do not have cell walls.
The cells serve different functions.
