Cellur structure Flashcards
What lies outside the nucleas?
cytoplasm
What is cytoplasm?
A substance which surronds the other cell structures
What does cytoplasm contain?
Ribosomes, mitochondria, endoplasmic reticulum, golgo apparatus, lysomes. centrosomes.
What are ribosomes?
Produce proteins
What is mitochondria?
produces energy
What is endoplasmic reticulum?
involved in the synthesis of proteins and fats.
What is lysomes?
help the cell manage waste
What is centrosomes?
important in guiding the cells reproductions.
Plant cells have rigid or narrow cell walls around the membrane?
Rigid
What does the cell wall do?
provide structure and support for cells
What does photosyntesis serve?
a source of energy for the cells and takes place in plant cells
What is cellur respiration?
process by which the mitochondria process sugar and oxygen to produce energy water and Carbon dioxide.
What does cellur respiration serve?
Energy source for animal cells
What does cell division do?
The process where genetic material is replicated in the nucleus
How does cancer occur?
when the signals are mutated and cells can grow without limit.
What is the longest part of cell division?
Interphase
What is the final phase of cell division?
Cytokinesis
what is cytokinesis?
Cytoplasm and cell membrane complete their separation and two daughter cells are formed
what is prophase?
chromtaids begin to pair up with their sister chromatids.
What is metaphase?
where the sister chromtaids move to opposite poles of the cell.
What is anaphase?
chromatids begin to pull apart into two seperate poles
What is anaphase?
chromatids begin to pull apart into two seperate poles
What is telophase?
the two nuclei become completely seperated
