Science Quiz 10/7 Flashcards
What is the function of the nucleus?
It’s the control center or the brain of the cell, it stores the DNA of the cell in it, and it controls cell growth and activities
What types of cells have a nucleus?
Eukaryotic cells
What is the function of a cell wall?
The cell wall is made of cellulose and gives support and shape to all plant cells. The structure is strong and rigid which allows the cell to be supported as turgor pressure increases.
What two parts are found in plant cells but not animal cells?
Chloroplasts and cell wall.
Which organelle is found in an animal cell but not a plant cell?
Lysosome
What is the function of ribosomes?
It makes the protein for the cell
What is the basic unit or building block of life?
Cells
What is the smallest unit of matter?
Atoms
A group of similar cells that work together to perform a specific job.
Tissue
What is an organism?
Anything that can independently carry out life processes
A group of organs that work together to perform body functions
Organ System
Large ecosystems with similar climates, animals, and vegetation.
Biome
Contains multiple populations of different species living in a common area.
Community
What is an individual?
One organism of a single species in an area
A community of biotic species and abiotic parts of an environment. For example: birds, trees, elephant, sun, rock, water
Ecosystem
Large neighboring biomes that interact across a planet. The term translates to “ball of sphere”. For example: the Earth
Biosphere
A group of similar cells that work together to perform a specific job.
Tissue
What are organs?
A combination of two or more tissues that work together to perform a specific function in the body.
List the levels of organization from cells to biosphere: (HINT: order matters and there are 11 to list)
Cells, Tissue, Organ, Organ System, Organism, Individual, Population, Community, Ecosystem, Biome, Biosphere
What does biotic mean?
Living
What does abiotic mean?
Non-Living
List all three parts of the cell theory:
Cells are the most basic units of life, all cells come from preexisting cells, and all living organisms are made up of one or more cells
The turning of all or part of a plant (and other organisms) in response to the direction of light.
Phototropism
The turning of all or part of a plant (and other organisms) in response to the sensation or downward pull of gravity.
Geotropism/Gravitropism
What is thigmotropism?
The turning of all or part of a plant (and other organisms) in response to touch
Define turgor pressure
The amount of pressure the vacuole puts on the cell membrane and cell wall
Which type of cell(s) contain the organelle called a vacuole?
Plant and animal cells
Which type of cell is larger, more complex, and generally rounder in shape? Eukaryotic or prokaryotic
Eukaryotic
What is the function of a vacuole?
To store food, water, and waste
What is the function of chloroplast?
To store chlorophyll, which absorbs and traps energy from the sun. This process is called photosynthesis
What is cytoplasm
Cytoplasm is the gel-like fluid that fills the inside of ALL types of cells. It is the fluid that all parts of cells float in.
Which type of cells contain ribosomes? Plant, Animal, Prokaryotic?
Ribosomes are in all types of cells.
What part of the cell surrounds the entire cell (like an outer skin) and controls what comes in and out of the cell?
The cell membrane
What is the mitochondria
Mitochondria is the “power house” organelle of cells. It converts food into energy (ATP).
