6 Characteristics of Living Things
Unicellular and multicellular are ways to describe this characteristic of living things.
Cellular Organization
The "powerhouse" of the cell
Mitochondria
This organelle is a storage area for the cell
Vacuole
The building blocks of life
Cells
These organisms make their own food
Autotrophs
This characteristic is why we get taller and smarter.
Grow and Develop
What organelle is the control center or "brain" of the cell?
Nucleus
These breakdown food particles for the cell
Lysosomes
Single-celled organisms are called
Unicellular
Organisms that cannot make their own food
Heterotrophs
The most abundant __________________ in cells is water.
Chemical of Life
The jelly-like substance that fills the empty space between the nucleus and the cell membrane
Cytoplasm
This passageway is like a maze that carries protein and other materials to the parts of the cell
Endoplasmic Reticulum
Organisms composed of many cells are called
Multicellular
The maintenance of a stable internal environment is called
Homeostasis
Cells need this in order to grow, repair injuries, or do any kind of work.
Energy Use
These organelles make proteins
Ribosomes
This is the rigid covering of a plant cell
Cell Wall
Organisms whose cells have no nucleus such as bacteria
Prokaryotes
This is the mistaken idea that living things can arise from nonliving things
spontaneous generation
The way that an organism reacts to a stimulus is called its _________________.
Response to surroundings
This organelle can be described as the "mailroom" of the cell because it packages and ships proteins and other materials.
Golgi Bodies
These organelles absorb sunlight and use it to make food for the cell. They also give plants their green color.
Chloroplasts
Organisms whose cells have a nucleus
Eukaryotes
Who was the first person to discover cells?
Robert Hooke
