Flashcards in Plant And Animal Cells Deck (17):
What makes up an animal cell?
What makes up a plant cell?
In the cell cytoplasm we have ...
What is an organelle?
Number of organised or specialised structures within a living cell
Cells that have a nucleus are called...
Describe the function of a cell membrane
Like a very thin bag
Holds cytoplasm and organelles
Controls what enters and leaves the cell e.g. Oxygen, carbon dioxide, glucose
Describe function of nucleus
Large structure that contains genes that control the activities of the cell . Genes in the chromosomes
Chromosomes are coiled DNA
Describe cytoplasms function
Jelly like substance that fills the cell
Lots of chemical reactions take place here
Describe the functions of mitochondria
Tiny structures where respiration takes place, releasing energy for cell processes
Just be seen with a light microscope
(Looks a bit like a jellybean)
Describe the function of ribosomes
Where proteins are made(protein synthesis)
Present in cytoplasm but not visible really, can't be seen with a light microscope
Describe the functions of the cell wall
Made of cellulose
Supports and protects the cell
Describe the functions of a vacuole
Stores cell sap
Helps to keep the cell firm and rigid
Describe function of chloroplasts
Contains chlorophyll, which traps energy transferred from the sun
Energy is used for photosynthesis
What does turgid mean
Muscle cells contain more mitochondria than skin cells. Why?
Muscle cells respire more
Need more energy
They carry out aerobic respiration and produce energy
Plants don't have skeletons. Suggest how they stand upright
Plant is supported by cell wall around each cell and the vacuole in each cell when it is full
