Cells Flashcards
2points of the cell theory
All living things are made of cells
All new cells arise from cells that already exist
What is an organism
Any living thing
Field of view
Circle of light you see when you look in microscope
What is an organelle
Parts/structure of a cell that have a specialized function
What is nucleus
Control centre of cell (brain)
Eukaryotic cell
Cell with a nuclear membrane
Prokaryotic cell
In some one celled organisms the nucleus has no membrane
Cell membrane
Holds the contents on cell in a place and also known as the gatekeeper
Cytoplasm
Watery fluid that takes up most of the cell
Vacuole
Stores water, nutrients and waste
Flagellum
A tail that moves the cell
Cilia
Tiny hairs that move the cell
Cell wall
Protects and supports plants
Chloroplast
Food factories of the plant, gets energy from sun
Contains chlorophyll
Mitochondria
Produces the energy for cell through cellular respiration
Power plant of cell
Cellular respiration
Process of converting food molecules to produce sugar energy for cells
Ribosomes
Where protein is produced/ synthesized
Endoplasmic reticulum
Material transport
Smooth no ribosomes
Rough has ribosomes- fuzzy dots
Golgi apparatus
Produces/stores and packages proteins and sends them out in vesicles to the surface of cell
Lysosomes
Recycling/ cleans cytoplasm
Breaks down larger molecules to smaller molecules so they can be cleaned up
What’s a wet mount
A glass slide holding specimen with a drop of water when using a microscope
Diffusion
Movement of a substance from a high concentration region to a region of low concentration – air freshener
Osmosis
Diffusion with water
Selectively permeable
Allows certain materials only to pass through membrane
Turgor pressure
The pressure exerted on a plant cell wall by water passing into the cell through osmosis
Chromosomes
Inside nucleus, contains DNA for cell (construction plans)
