Cells End Of Year Test Flashcards
What organelles do animal cells have
Cell membrane
Nucleus
Cytoplasm
Mitochondria
What is the cell membranes job
Protects the cell controls what substances go in and out as well
What is cytoplasms job
It forms the body of the cell dissolves chemicals and stored food
What is the job of the nucleus
It controls the activity of the cell and contains DNA
What is the job of mitochondria
Mitochondria is where respiration reactions happen
What is vacuoles job
It contains cell sap which keeps the cell firm
What is the cell walls job
It protects and supports the cell
It is made from cellulose
What is the job of the chloroplasts
It contains chlorophyll which absorbs light and energy photosynthesis
What is a specialised cell
A specialised cell is a cell that has been specifically adapted to its function/job
What is the palisade cells job
It is only found in the leaf of a plant
It contains lots of chloroplasts of photosynthesis
What is the red blood cells job
It carries blood around the body
It is tourist ( doughnut) shaped with a large surface area
It does not contain a nucleus
What is the sperm cells job
It has a long tail (flagellum) to allow it to swim fast towards the egg
It has lots of mitochondria to provide energy for swimming
What is the ciliated epithelial cells job
It is found in the nose and the lungs
The small hairs ( cilia) move dust and bacteria to the back of the throat where they are swallowed
What it’s the ovum ( egg cells) job
It has a large store of nutrients for the embryo
It contains genetic information from the mother inside the the nucleus
What is the root hair cells job
It absorbs water and minerals form the soil
It has a large surface area to absorption
It has a lot of mitochondria to provide energy
It contains no chloroplasts because it is underground and dose photosynthesise
What is a group of similar cells working together called?
A tissue
What is an organ?
An organ is made up of different tissues working together
What is an organ system. Give an example
Organs working together e.g the digestive system
Name 3 differences between a plant and an animal cell
Plant cells have:
- chloroplasts
- A Cell wall
- A vacuole
What does the cell membrane do?
It protects the cell and controls what goes in and out as well.
It controls what passes in and out of the cell
What does the cell wall do
It gives the plant cell extra strength and support
What is a specialised cell
A cell that has a certain feature or has changed it’s shape to do a particular job
A group of similar cells carrying out the same job are called a…
Tissue
What is the job of a leaf
Photosynthesis
