Cells And Cell Structure Flashcards
What are the main parts of animal cells?
- nucleus
- cytoplasm
- cell membrane
- mitochondria
- ribosomes
Which part of a cell are found in plant cells not animal cells?
- cell wall
- chloroplast
- vacuole
What is the function of a nucleus of a cell?
Contains genetic material, which controls the activity of the cell
What is the function of the cytoplasm?
Most chemical processes take place here, controlled by enzymes
What is the function of the cell membrane?
Controls the movement of substances into and out of the cell
What is the function of the mitochondria?
Most energy is released by respiration here
Where does protein synthesis in the cell happen?
On the ribosomes in the cytoplasm
Which features do plant cells have which strengthen their cell?
Plant cells have a cell wall.
What is the function of the chloroplast in plant cells?
Contains chlorophyll which absorbs energy for photosynthesis
What is the function of vacuole and what is found in it?
The vacuole is filled with cell sap to keep the cell rigid
What is significant about the genetic information of s bacteria cell?
The genes are not in a distinct nucleus
What is missing from a red blood cell?
The nucleus
What are cells with different functions called?
Specialised cells
What are the adaptations of a sperm cell?
Head contains enzymes to penetrate egg and lots of mitochondria so the sperm has enough energy to swim to the egg
