cells
what is the vacuole
a sac shaped pod storing water, food/nutrients and waste products.
Chloroplast
photosynthesis, using sunlight, water, and carbon dioxide to create energy.
nucleus
contains the cell's genetic material
How technology advancements influenced cell theory
Helping us see more how cells work with microscopes. And seeing the structure of them.
what is cytoplasm
jelly like substance inside a cell,outside the nucleus, that fills the cell and surrounds the organelles.
What are mitochondria
organelles that act as the "powerhouses" by generating most of the cell's energy.
What is a cell wall
a rigid or flexible layer that surrounds and supports the cell membrane, providing structural support, shape, and protection to cells of most plants, algae, fungi, and bacteria.
Know the 3 functions of all cells:
1. Getting rid of waste.
2. Obtaining energy.
3. Bringing in nutrients and water.
What is ribosome
a complex molecular machine found in all living cells that synthesizes proteins.
what are the 3 points of cell theory
1. All cells come from existing cells.
2. All living things are made of cells.
3. Cells are the basic unit of structure and function.
What is a cell membrane
semipermeable barrier that surrounds all living cells, separating their internal components from the external environment.
Know the basic difference between an electron microscope and a light microscope-
light microscopes use visible light to magnify, while electron microscopes use a beam of electrons for much higher magnification and resolution.
What is lysosome
a membrane-bound organelle within a cell that contains digestive enzymes to break down waste materials and cellular debris.
Golgi apparatus
a cell organelle that processes, packages, and sorts proteins and lipids for transport.
What are the relationships between cells , tissues, organs and organ systems
cells form tissues, tissues form organs, and organs form organ systems.
Compare and contrast the structure and function of:Multicellular and Unicellur
Multicellular- unspecialized cells that share all life, demonstrating a cooperative but less differentiated structure functions. Unicellur- A single cell carries out all life functions simple organisms
compare and contrast plant and animal cells
plant cells have a cell wall and animal cells don't.
Endoplasmic reticulum
a network of membranes within a cell that is essential for protein.
what is the differents between cell walls and cell membrane.
Cell walls provide rigid structural support and protection while cell membranes are flexible and regulate what goes in and out of the cell.
