Cells
True of false: all bacteria are harmful.
False
some are beneficial
What is the name for the process in which plants make their food?
Photosynthesis
What do flowers do in the Spring?
Flowers bloom
How is pollen transported?
By wind and insects (called pollinators)
What is the difference between unicellular and multicellular organisms?
Multicellular organisms have many cells
Unicellular organisms have one cell
Name a fungus! (fungus = singular of fungi)
mushrooms, mold, yeast
What do the leaves of the plant absorb?
Sunlight and CO2
What is the definition of an interaction (in the context of plants)?
An interaction (in plants) is the reaction to the changes in the environment.
What are the 4 stages of reproduction for plants?
Pollination, fertilisation, seed and fruit formation, germination
What is the job of the nucleus?
To control the cell's activity
like the brain of the cell
Which type of living organism is multicellular, heterotrophic, and can move on its own?
Animals!
When do plants release O2?
When do they release CO2?
O2 during photosynthesis
CO2 during respiration
What is the name for the types of trees that lose their leaves in autumn?
Deciduous
Pollination happens when the pollen from the ______ of one flower moves to the ______ of another.
Stamen (male part)
Stigma (female part)
True or false: The nucleus contains organelles, which perform different functions.
False
This is the cytoplasm
Which living organism is multicellular, autotrophic, and can't move on its own?
Plants
What do you call the mix of water and minerals that the plant initially absorbs from the soil?
What is a reaction / interaction that only happens in some plants ?
Contact: Some plants can produce toxic substances to stop insects attacking them. Others close their leaves when they are touched.
What happens at the fertilization stage?
The pollen grain and the ovule join together.
What is the function of the cell membrane?
It surrounds and protects the cell.
How are protazoa and bacteria similar and different in their qualities? (think cells, how they eat)
Protozoa can be unicellular and multicellular. Bacteria are only unicellular. Both can be heterotrophic and autotrophic.
How is phloem sap created? (what is combined to make it?)
Xylem sap + Sunlight + CO2
What are similarities and differences between the plant's interaction with light and the plant's interaction with water?
Similarities: Roots and stems both grow as part of the interaction (stem towards the light, roots towards the water). Both are how plants grow / move to bring the most nutrition to the plants.
Differences: the light interaction concerns the stem and growing up towards the light. The water interaction concerns the roots and growing where there is water in the soil.
Light: The stem grows towards the light. The leaves change their orientation to follow the Sun during the day.
Water: Roots grow in areas where the soil has the minerals and water they need.
What is the process of seed formation? and fruit formation?
The fertilized ovule forms an embryo. The embryo develops into a seed.
The pistil grows and develops into a fruit.
embryo ------------------- seed ------------------ fruit
