Cells
What is the control center of a cell?
nucleus
What is photosynthesis? What does a plant need to carry out photosynthesis?
The process where plants use energy from the sun to make food. They need sunlight, water and carbon dioxide.
What are the building blocks of all living things?
(also the smallest unit of living matter)
cells
This structure takes in water and nutrients from the soil
roots
Sunlight and rocks are examples of:
biotic factors or abiotic factors
abiotic factors - they are not living
The organelles that supply energy to the cell are called?
mitochondria
What is the food that is produced by plants during photosynthesis
Bonus - what is also created during photosynthesis?
sugar (or glucose)
oxygen is also produced during photosynthesis
All of the following are needs of living things except:
water food communication gases shelter
communication
Stomata are very important plant structures that allow gases and water to move in and out. Where are stomata located?
underneath the leaves
A chemical reaction creates a new substance.
What are 3 indicators that a chemical reaction has occurred?
change in odor, change in color, energy change (heat or light is created) gas is created (bubbles) and a precipitate is formed (a solid)
What is the name of the extra border around the cell that is found only in plant cells?
Extra 300 pt.s - what can pass through this extra barrier?
cell wall
Water, oxygen, carbon dioxide and other substances can pass through the cell wall
Where is the part of the plant where photosynthesis takes place?
In the leaves
The gel-like substance that fills cells is called what?
cytoplasm
Bonus extra 300 pts. True or False
Cytoplasm is only in animals cells and not in plant cells
What is the part of the plant used for reproduction?
Bonus - extra 300 pt.s Name the female and male parts of this structure
flower
Female part is the pistil
Male part is the stamen
An ice cube melts into a puddle of water.
This is a chemical change or a physical change?
physical change
What is the main function of vacuoles?
And - True or False - most plant cells contain a single large vacuole?
They store materials such as water, proteins, carbohydrates and wastes.
True - most plants have 1 vacuole
Why do both plants and animals depend on photosynthesis?
Plants create their own food with photosynthesis and animals rely on plants for their food. (herbivores are animals that eat plants to survive)
Adaptations are special features that allow a plant or animal to live in a particular place or habitat.
List 2 different kinds of plant adaptations
reproducing without seeds floating plants
night blooming thick bark
colorful flowers waxy or pointy leaves
thorns long or short root systems
poisonous parts
The tissue that transports water and nutrients up the stem and throughout the plant is called?
xylem
A mixture of substances that are blended so completely that the mixture looks the same everywhere is called a _____?
solution
Ribosomes are important parts of cells because they make what important substance?
Proteins - which are important for growth and repair of cells
What is the difference between chloroplasts and chlorophyll? Describe their functions
Chloroplasts are structures in leaves that collect sunlight and is where photosynthesis takes place.
Chloroplasts contain the chlorophyll - which is a green pigments that traps the energy from the sun.
What is the process of transpiration?
The release of water into the air. It happens when water evaporates from the leaves of plants.
Besides the cell wall, name 2 things in plant cells that are not found in animal cells?
chloroplasts and chlorophyll
Name at least 3 characteristics of metals
conducts heat and electricity, has a shiny luster, malleable (can be hammered) and ductile (can be drawn out into wires)
