Cell Structure Flashcards
Cell Membrane
Made up of phospholipids and proteins
Phospholipid bilayer
Chromatin
Non-dividing chromosomes
Elongated and interwoven
Nucleus function
Controls the cell activities
Contains chromosomes, the cells genetic information
DNA
Deoxyribonucleic acid
In chromosomes in the nucleus
Nucleolus fucntion
In nucleus
Contains RNA, DNA and protein
Makes ribosomes
Cell Wall
In plants
Made of cellulose
Supports and strengthens the cell
Vacuoles
Plants mostly Contains cell sap Strengthen the cell Storage Waste disposal
Ribosomes
Make protein
Mitochondrion
Provides energy by respiration
Active cells
Infoldings imply large energy output
More infoldings = more energy
Chromosomes
Green
Carry out photosynthesis
Prokaryotic Cells
No nucleus
No membrane enclosed organelles
Small and primitive
Bacteria
Eukaryotic Cells
Membrane-enclosed nucleus and cell organelles
Larger and more advanced
Plants, animal, fungi, and amoeba
The cell
The smallest unit of matter that can carry on all the processes of life
Organelle
A cell component that performs specific functions for the cell
Cell membrane function
- Controls entry and exit of molecules to the cell across its semi permeable membrane
- Separate the cell organelles and cytoplasm from the outside
- Membranes give some support to the cell
