Cell Organelles (Unit 3 - Part 2) Flashcards
Organelles
Tiny organs inside a cell
Organelles are part of the levels of…
organization in living things
All cells have a….
membrane, nucleus (DNA), cytoplasm
Nucleus
A cell’s control center
The nucleus…
contains the cell’s DNA and regulates the cell’s activities
Ribsomes
Where protein synthesis occurs (where proteins are made)
Ribosomes…
are tiny dots, and they are either free floating or on an organelle called the endoplasmic reticulum
Vacuoles
Store food, water, and waste
Vesicles
Move materials in and out of the cell
Vesicles/Vacuoles
Membrane bound storage organelles
Lysosomes
Specialized vacuoles with digestive enzymes to break down food or foreign invaders
Mitochondria
Where food is turned into useful energy (ATP)
Cellular Respiration
The process of turning food into energy
What are some examples of cells that need lots of mitochondria because they need lots of energy?
Heart cell, nerve cell, and muscle cell
Flagella and Cilia
Hair-like organelles that help cells to move
Motile
Organisms and cells that can move
Nonmotile
Organisms and cells that can not move
The organelles found in ONLY in plant cells are..
Cell walls and chloroplast
Cell Wall
Supports plant cells and prevents them from bursting in water
the cell wall is located…
outside of the cell membrane
Chloroplast
performs photosynthesis
Photosynthesis
a plant uses Carbon Dioxide, water, and energy from the sun to make food in the form of glucose
Chloroplast are located..
in the leaves of a plant
Chloroplasts gives plants..
their green color
Cytoplasm
jelly-like substance that holds organelles in place and it is made mostly of water
Cell membrane
controls what goes into and out of the cell and it separates the cell from the environment
