Cells
What is the nucleus?
The "brain" of the cell, it controls everything inside the cell.
What is a tissue? Are all tissues the same?
A tissue is a group of cells. Tissues have different functions.
Where does photosynthesis happen?
It happens in the leaf.
Example of interaction
Birds build nests, frogs dig burros, animals run from danger, we duck when something is thrown at us
Example of interaction
roots grow towards water, leaves grow towards sunlight, Sunflowers follow the sun
Are all cells the same? Why?
No, they all have different shapes and functions.
How are plant and animal cells similar?
Both plant and animal cells have: a nucleus, membrane, cytoplasm, organelles, vacuoles, and a cell wall.
How are plant and animal cells different?
The cell wall is rigid in plants. Plants have chlorophyll.
How do vertebrates or fish get oxygen?
Vertebrates breathe the air, fish absorb oxygen form the water
What is raw sap and elaborate sap?
Raw sap = water and minerals, Elaborate sap = nutrients
What are the 3 types of living things?
Animals, plants, and bacteria.
What is an organ? Give 2 examples in animals.
An organ is made of different tissue.
Ex. heart, brain, lungs, skin.
What are the 3 main parts of a plant?
Leaves (makes food/photosynthesis), Stem (supports the plant and transports water/nutrients), Roots (absorb water and nutrients from the soil)
What are the two reproductive processes
Asexual reproduction and sexual reproduction
What is a seed plant? Example?
A plant that reproduces with seeds. Oak trees, pine trees, rose bushes, apple trees.
What are the Basic Life Processes?
Interaction, Nutrition, Reproduction
What is a type of cell in animals? What is it's function?
Red blood cells: carry oxygen.
Nerve cells: transmit nerve impulses to and from the brain.
Reproductive cells: fertilization (lets animals reproduce).
What is photosynthesis?
Transforming sunlight, water, mineral salts, and carbon dioxide into nutrients/food
What are the 3 types of sexual reproduction?
Oviparous (lay eggs), Viviparous (grow babies inside a body), Ovoviviparous (eggs hatch inside a body)
What is a non-seed plant? How do they reproduce? Example?
What are unicellular and multicellular organisms? Give an example of both.
Unicellular organisms only have one cell.
ex. Bacteria, yeast.
Multicellular organisms have more than one cell.
ex. Animals, plants.
What is a system? What are 2 systems in humans?
A system if a group of organs working together to perform a function.
The circulatory system (nutrition), the nervous system (interaction), the respiratory system.
What is a plant organ and system? What are their functions?
A leaf is an organ, it absorbs sunlight and carbon dioxide.
The vascular system transports water, mineral salts, and nutrients.
What systems are used to interact with the environment?
The locomotor and nervous system
(1)Roots absorb water/minerals to make raw sap, (2)raw sap goes up the stem, (3)CO2 enters the leaf through stomata, (4)photosynthesis, sunlight/CO2 convert raw sap into elaborate sap, (5)elaborate sap gets to other parts of the plant as food
