Characteristics of Life
All living things must be made of these.
What are cells?
This man observed cork with his microscope and called the tiny boxes "cells"
Who is Robert Hooke?
This organelle provides the cell with the energy it needs to perform its function and activities.
What is the mitochondria?
This occurs when particles of a substance move from an area of high concentration to an area of low concentration.
What is diffusion.
This organelle is found in both plant and animal cells that help make up the external boundary of the cells.
What is a cell membrane?
Sexual and asexual are examples of this.
What is reproduction?
This cell type contains a nucleus and organelles (such as mitochondria).
What are eukaryotic cells?
This organelle directs cell processes by providing DNA instructions. It is surrounded by its own membrane and is covered with pores.
What is the nucleus?
The type of diffusion that occurs when a transport protein is required to move large molecules through the membrane.
What is facilitated diffusion?
This type of transport requires energy because molecules are going against the concentration gradient.
What is active transport?
When you look into the light and your pupil shrinks is an example of this characteristic.
What is respond to the environment?
What is a prokaryotic cell?
This organelle is a series of flattened membranes. Cell products pass through these membranes and become packaged for delivery in or out of the cell.
What is the Golgi apparatus?
This is the diffusion of water.
What is osmosis?
This organelle is found only in plant cells.
What are chloroplasts? (large central vacuole, cell wall)
Organisms will either exhibit this trait as autotrophic or heterotrophic.
What is obtain and use energy?
Which part of the cell theory is also a characteristic of life?
What is all organisms are made of cells?
This organelle is a series of interconnected passageways. Proteins and lipids are synthesized here also. There are two varieties 'S' and 'R'.
What is endoplasmic reticulum?
This term refers to the direction the particles are moving; you are either going with it or against it.
What is the concentration gradient?
What is the function of the ribosome?
What is to make proteins?
The ability to maintain a stable internal environment.
What is homeostasis?
The three parts of the cell theory.
What are:
1. All living things are made of cells.
2. Cells are the basic unit of life.
3. Cells only come from other cells.
This organelle is found only in animal cells. It is made of microtubules and is thought to play a role in cell division.
What are centrioles?
When water moves into a cell from the surrounding environment and it gains mass it is said to be in this type of solution.
What is hypotonic?
This type of cells may need many mitochondrion due to their need for lots of energy.
What are muscle cells?
