Cell Functions
Cells produce the energy they need to survive through this process.
Cellular Respiration
The large, round organelle in a eukaryotic cell that houses genetic material.
nucleus
The sequence of structures from least complex to most complex: chloroplast → plant cell → leaf → rosebush.
chloroplast, plant cell, leaf, rosebush
If a cell were a school, the nucleus would represent this.
principal
This 17th-century scientist discovered cells.
Robert Hooke
What is the basic function of a cell?
respiration, ingestion, reproduction
Both the cell wall and cell membrane perform this essential function.
providing protection
The heart is classified as this level of organization.
organ
If a cell were a school, the cell membrane would most likely be represented by this.
walls and doors
This scientist concluded all living things arise from cells and that cells come from other cells.
René Henri Dutrochet
All cells carry out this process to sustain life.
Using and needing energy
If cells were a school, this part would represent the cell membrane.
walls and doors
The five levels of organization in living things are:
cell, tissue, organ, organ system, organism
If a school cafeteria cooked all the meals, it would be similar to this organelle’s function.
chloroplast or mitochondria
All cells need this to survive, whether plant or animal.
energy
Multiple organelles are required for this reason in the animal cell cycle.
because different organelles are specialized for different functions
All plant cells contain these organelles necessary for photosynthesis.
chloroplasts
These four human tissues are all made up of cells.
muscle, nervous, connective, and epithelial tissues
The hallways and teachers who control what moves in and out of a school would be like this in a cell.
cell membrane
The specialized structures in cells that perform specific functions are called this.
organelles
A disorder in this organelle will directly affect the cell’s energy levels.
mitochondria
This organelle is shaped like a “powerhouse” and releases energy for the cell.
mitochondria
According to Dutrochet, all living things arise from this.
cells
The classrooms where instructions and information are stored are like this in a cell.
nucleus
These plant structures are green and help convert sunlight into energy for the cell.
