Cell Structure
Controls what enters and leaves the cell. "the security guard"
Cell membrane
Stores DNA, which contains instructions that direct the cell’s activities. "The brain"
Nucleus
All living things are made of these
Cells
Between a water molecule and a cell, this is larger
Cell
A community of microorganisms in an environment. Examples: Skin, Gut, Eyes
Microbiome
The space that supports cell parts. Many cell reactions happen here. "The workspace"
Cytoplasm
Stores water, nutrients, and waste. "the storage tank"
Vacuole
Builds proteins that cells need to grow, repair damage, and do their jobs. "The assembly line workers" "the builders"
Ribosomes
Between a micrometer and a nanometer, this is the larger unit.
Micrometer
Something that is too small to see with the naked eye.
Microscopic
Breaks down food molecules to make ATP, the cell’s usable energy supply. "The power plant"
Mitochondria
Uses enzymes to break down worn-out cell parts, waste, and harmful bacteria. "the recYcLer"
Lysosome
cell structures with specific jobs.
Organelles
There are this many molecules in a cell
billions
a visible group of many microorganisms growing together. Hint: Bacteria in the petri dish
Colony
Sorts and packages proteins and fats, then sends them where they are needed. "The post office"
Golgi Apparatus
Organizes the fibers that separate chromosomes during cell division. "the coach"
Centrosome
These cells have no nucleus, they are Single-celled organisms like bacteria
PROKARYOTIC cells
These five objects arranged from smallest to largest: human, bacterium, water molecule, grain of salt, skin cell.
water molecule - bacterium - skin cell - grain of salt- human?
Nearly all cells are microscopic. Name one cell you CAN see with the naked eye
Human Egg Cell
Makes fats and some hormones, stores calcium, and helps break down harmful substances. "the lab"
Smooth Endoplasmic Reticulum (smoooth ER)
Ribosomes on its surface make proteins. It folds and prepares them for transport. "the assembly line"
Rough Endoplasmic Reticulum (Rough ER)
These cells have DNA in a nucleus they have one or many cells. Examples are Plants, animals, and fungi.
Eukaryotic Cells
This many micrometers equal 1 millimeter
1000
In 1665, he saw tiny compartments in cork and called them “cells.”
