Life
All living things are made of one or more of these, which are considered the basic units of life.
What are cells?
This scientist was the first to observe and name “cells” after looking at cork under a microscope.
Who is Robert Hooke?
This organelle is the control center of the cell and contains the cell’s DNA.
What is the nucleus?
This type of cell transport moves substances from an area of high concentration to low concentration without using energy.
What is passive transport?
This type of solution would cause a cell to swell.
What is hypotonic?
A plant growing from a seed into a mature tree demonstrates this characteristic of life.
What is growth and development?
This scientist observed living microorganisms in pond water using a microscope.
Who is Leeuwenhoek?
Known as the powerhouse of the cell, this organelle releases energy from food through cellular respiration.
What is the mitochondria?
This type of passive transport is the movement of water across a selectively permeable membrane.
What is osmosis?
These organelles are involved in energy conversion.
What are mitochondria and chloroplast?
A person sweating on a hot day demonstrates this characteristic of life.
What is maintaining homeostasis?
This scientist concluded that all plants are made of cells.
Who is Matthias Schleiden?
Found in plant cells, this organelle contains chlorophyll and captures light energy for photosynthesis.
What is the chloroplast?
During this process, molecules move from an area of high concentration to low concentration until they are evenly distributed.
What is diffusion?
A person sweating when they become too hot demonstrates this characteristic of life that keeps internal conditions stable.
What is homeostasis?
A rabbit runs away when it hears a loud noise. Which characteristic of life is shown?
What is responding to stimuli?
This scientist concluded that all animals are made of cells.
Who is Theodor Schwann?
This organelle is responsible for making proteins and may be found floating in the cytoplasm or attached to the rough ER.
What is the ribosome?
Unlike passive transport, this type of transport requires the cell to use energy (ATP) and can move substances from low to high concentration.
What is active transport?
This scientist determined that cells come from pre-existing cells.
Who is Rudolph Virchow?
Scientists discover an organism that grows, uses energy, and reproduces. To confirm it is living, they find this molecule carrying genetic information. What is this molecule?
What is DNA?
State the three main parts of the Cell Theory.
What are: 1. All living things are made of one or more cells. 2. The cell is the basic unit of structure and function in living things. 3. All cells come from pre-existing cells.
This organelle modifies, sorts, packages, and ships proteins to different locations in or outside the cell.
What is the Golgi body?
A cell surrounds and engulfs a large particle, bringing it into the cell inside a vesicle. This form of active transport is called this.
What is endocytosis?
These 3 organelles are only found in a plant cell.
What are chloroplasts, the cell wall, and the central vacuole?
