Cell Structure and function 1
Rigid, outer layer that protects outside of plant cells.
Cell Wall
Directs activity in the cell and holds genetic information.
Nucleus
Tiny structures inside a cell which carry out specific functions.
Organelle
Usually contain a nucleus.
Eukaryotic Cells
These types of transport do not require energy.
Passive transport
Protects inside of cell and regulates what enters and leaves the cell.
Cell Membrane
Which organelles are unique to plant cells?
Chloroplasts and cell walls
The membrane surrounding the nucleus.
Nuclear envelope
Describe the rough ER
ER that is studded with Ribosomes-
Ribosomes are on the ER
These types of transport do require energy.
Active transport.
A solution that has fewer solutes that the cell would be
Hypotonic- Water would rush out of the cell then
Tiny structures that make proteins.
Ribosome
Captures sunlight and converts it into energy in green plants.
Chloroplast.
A protein that detects a signal molecule and performs an action in response is called a
Receptor
During passive transport, molecules move from a ___ concentration to a _____ concentration.
High to Low
Structure within the nucleus produces dot like ribosomes
Nucleolus
Network of passageways that make and store lipids.
Smooth Endoplasmic Reticulum
Breaks down cell parts for digestion.
Lysosome
Transport proteins play a role in both a- passive and active transport b-diffusion and vesicle transport c- phagocytosis and passive transport
Both passive and Active transport
Diffusion of water.
Osmosis
Jelly-like substance between nucleus and cell membrane.
Cytoplasm
The powerhouse of the cell - converts energy in food to energy the cell needs.
Mitochondria
Collects, modifies, and packages proteins for different jobs then sends them out.
Golgi Apparatus
State the 3 principals of the cell theory
1. Cells are the basic unit of life
2. All living things are made up of cells
3. New cells come from old cells
During active transport, molecules move from a ___ concentration to a _____ concentration.
Low to High
