Study Quiz 2 Flashcards
What is the function of the Nucleus?
The Nucelus makes all of the decisions in the cell, which includes storing its DNA, and maintaining its integrity.
What types of cells have a Nucleus?
Both Animal and Plant 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, & Cell Wall
Which organelle is found in an animal cell but not a plant cell?
Ribosome
What is the function of ribosomes?
It creates the Protein for the cell.
What is the basic unit or building block of life?
DNA
What is the smallest unit of matter?
Atom
What is the function of an organelle?
A group of similar cells that work together to perform a specific job.
What is an organism?
A single-celled plant, or animal.
What is the function of an Organ System?
A group of organs that work together to perform body functions.
What is a Biome?
Large ecosystems with similar climate, animals, and vegetation.
What is a community?
Contains multiple populations of different species living in a common area.
What is an individual?
One organism of single species in an area.
What is an ecosystem?
A community of biotic species and abiotic parts of an environment.
What is a Biosphere?
Large neighboring biomes interact across a planet. The term translates to “ball of sphere”.
What is the Tissue?
A group of similar cells that work together to perform a specific job.
What are organs?
A combination of one or more tissues that work together to perform body functions.
List the levels of organization from cells to biosphere.
Cells, Tissue, Organ, Organ System, Organism, individual, population, Community, Ecosystem, Biome, & Biosphere.
What does biotic mean?
Biotic = Living
What does abiotic mean?
Abiotic = Not Living
List all three parts of the cell theory:
All living organisms are made up of one or more cells, Cells are the basic unit of life, & All cells arise from pre-existing cells.
What Is Phototropism?
The turning of all or part of a plant (and other organisms) in response to the direction of light.
What is Gravitropism?
The turning of all or part of a plant (and other organisms) in response to the sensation or downward pull of gravity.
What is thigmotropism?
When a plant responds to when it touches something. EX: A vine wrapping around a Woden pole.
Define turgor pressure.
When water fills up in the vacuole, and pushes against the cell wall.
Which type of cell(s) contain the organelle called a valcuole?
Plant Cell
Which type of cell is larger, more complex, and generally rounder in shape? Eukaryotic or Prokaryotic?
Eukaryotic
What is the function of a Vacuole?
The Vacuole stores water, food, and waste in the cell.
What is the function of chloroplast?
The Chloroplast captures radiant energy from the sun and turns it into pigment for the plant.
What is the function of the 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?
Animal Cells, and Prokaryotic Cells.
What part of the cell surrounds the entire cell (like an outer skin) and controls what comes in and out of the cell?
Whatis the function of Mitochondria?
Mitochondria is the “power house” organelle of cells. It converts food into energy. (ATP)
