Cells/Mitosis/Miosis/cellcycle Flashcards
Cell theory ๐
๐1: all living organisms are composed of one or more cells
๐2: Cells are the basic unit of structure and function
๐3: All cells come from pre-existing cells
๐4: the activity of an entire organism depends on the total activity of its indรฉpendant cells
Cell Types??๐ฑ
- Prokaryotic (bacterium)
* Eukaryotic (found in plants&animals)
Eukaryotic Cells ๐ณ๐ฆ
It is an organism thatโs cells have their DNA contained in a nucleus
Found inโฆ
- fungi
- plant cells
- animal cells
- protests
Prokaryotic Cells ๐คฎ
Itโs a cell that does not have a nucleus to contain their DNA
This is a bacterium cell
Cell wall ๐ด
Rigid tough wall made of cellulose only found in Plant Cells
*protects and supports the cell
Cell membrane ๐ฉ
A thin covering that goes around the cell
- protects + moves materials in and out of the cell ^communication^
Both plant + animal cells
Cytoplasm ๐
Jelly-like substance that contains organelles
*pads and supports organelles
Both plant + animal cells
Nucleus ๐ด
Dense ball shaped structure containing DNA
*controls all the cells activities
both plant+animal cells
Nuclear Membrane ๐บ
Thin covering over the nucleus
- covers and protects the nucleus
Both plant+animal cellls
Nucleolus ใฐ๏ธ
Small dark area in the nucleus
*produces ribosomes
Both plant+animal cells
Chromatin โ๏ธ
In the nucleus/made of DNA & protein / contains genes/ Chromatin is unraveled chromosomes
*provides instructions for the cells activities (growth&reproduction)
Both plant+ animal cells
Endoplasmic reticulum ๐
Clear tubular system of tunnels throughout cell ๐ซ
*transports materials like protein around the cell
Both plant+animal cells
Ribosomes ๐ฏ๐ฏ๐ฏ
Small specks made of RNA/found in cytoplasm or on the endoplasmic reticulum.
*makes proteins
Both plants + animals cells
Mitochondria ๐
Location in the cytoplasm (bean shaped)
Powerhouse of the cell!!
*supplies energy for the cells
Vacuole ๐
Large open storage area, smaller in animal cells
*storage tank for food, water, waste, or enzymes
Both plant and animal cells
