Organelles 1
This organelle controls what enters or leaves the cell
cell membrane
These structures may be found floating freely in the cytoplasm or attached to the endoplasmic reticulum.
Ribosomes
A basic unit of structure and function in a living organism.
What is a cell?
Plants cells use this process to make food.
What is photosynthesis?
This occurs when particles of a substance move from there there are many particles to where there are few particles
Diffusion
This is the smallest unit of an organism that is classified as living.
cells
the portion of the cell within the membrane that includes a "jelly" like fluid and all organelles except for the nucleus.
cytoplasm
This organelle converts glucose and other organic molecules into a form of usable cell energy called ATP.
Mitochondria
Every living organism is made of these.
What are cells?
What are the reactants (inputs) for photosynthesis
Carbon Dioxide, Water, and Light
Osmosis
Rocks, pens, and tables are examples of these things.
What are non-living things
This organelle is the rigid outer layer.
cell wall
An organelle found in plant cells but not in animal cells.
What is choloplasts?
Living things with one cell are called this.
What is unicellular?
These are the products (outputs) of photosynthesis
Glucose and Oxygen
The term refers to the direction the particles are moving; you are either going with it or against it.
Concentration gradient
People, plants, and bacteria are consider these.
controls all the activities of the cell, including cell reproduction and protein synthesis
Nucleus
This organelle breaks down material.
What are lyosomes?
Living things with two cells are called this.
What is multicellular?
Photosynthesis occurs in this organelle of plant cells
Chloroplasts
The sodium/potassium pump requires ATP energy to pump against the concentration gradient. This is an example of this type of transport.
Active Transport
One specific characteristic of living things
- Breathing out CO2 is known as...
What is excretion?
What organelles does a plant cell have that an animal cell does not?
chloroplast and cell wall
This organelle makes glucose.
chloroplasts
Scientists use compound light, or electron tools to observe cells.
What is a microscope?
Cells who require more energy produce more of these.
What is mitochondria?
Large molecules that cannot pass through the phospholipid bilayer must pass through these
Protein channel (transport proteins)
This man observed cork with his microscope and celled the tiny boxes 'cells' which started our understanding of living things.
Robert Hooke
What is the special property of the cell membrane make up that allows this phospholipid bi-layer to develop?
Hydrophobic and hydrophillic ends
This organelle is the storage area.
vacuole
Robert Hooke, Anton van Leeuwenhoek, Theodor Schwann, Rudolf Virchow, and Matthias Schliden were all responsible for this theory.
The Cell Theory
involves animals and plants taking in glucose (chemical energy) and oxygen. The products are?
carbon dioxide, water, and ATP energy
All living things need to maintain a stable internal environment. This is known as...
Homeostasis
All living things are classified into 2 category prokaryotes or eukaryotes
Name an prokaryote organism ?
Name an eukaryote organisms?
Bacteria are prokaryotes.
Animals, Plants, Fungi, and Protists are eukaryotes.
This organelle digests worn out cell parts and kills invading organisms
lysosome
This organelle is made of microtubules/centrioles and is thought to play a role in cell division.
cytoskeleton
The three parts of the cell theory include:
The following three characteristics are part of what theory?
All organisms are composed of one or more cells.
The cell is the basic unit of structure and organization in organisms.
All cells come from pre-existing cells.
What is the chemical equation for photosynthesis
6CO2+6H2O+Light--C6H12O6+O2
The type of diffusion that occurs when a transport protein is required to move large molecules along with concentration gradient
Facilitated diffusion
What Living Thing Charactersitcs is described below:
What happens when your body temperature gets too high?
What happens when your body temperature gets too low?
Respond to your environment
-You sweat/ blood rises to the surface
-You shiver/ get goose bumps/ blood travels to the core.
