Plant structure I
The main supporting structure of a plant
What is the stem
It anchors a plant in the ground, absorb water and minerals from the soil, and sometimes store food.
What are roots
It capture the sun's energy and carry out the food-making process of photosynthesis.
what are the leaves
Cytokinins promote what in cells?
Cell Division
A plant tilts toward it due to a tropism.
What is light?
This transports water and minerals
What is xylem
Fibrous and taproot are the two main types of this.
What is root system?
Bottom of the pistil, where eggs develop. eventually turns into fruit.
What is an ovary?
Biologists add cytokinins to plant cells for this reason
To stimulate cell division
Regulates a plant's development.
What are hormones?
This transports food
What is phloem
This carries substances between the plant's roots and leaves.
What is a stem?
This happens when it lands in an area with favorable conditions and a new plant sprouts.
When does a seed become a plant?
This occurs during fruit ripening
Starch is converted to sugar, protective toxins are removed/destroyed, chlorophyll is broken down, cell walls are degraded, pigments and aromas that signal ripeness are produced.
It inhibits vegetative growth by restricting cell elongation, it promotes fruit ripening, flower wilting, and leaf fall.
What is ethylene?
What does the cuticle of a plant do?
Helps prevent water loss
Those can be either woody or herbaceous.
What are stems?
Those are the male reproductive parts..
What are stamens?
A plant's reaction to environmental stimuli.
What is/are tropism(s)?
Stimulates shoot elongation, seed germination, and fruit and flower maturation.
What are gibberellins?
Opening or pores in the leaf are called
stoma/stomata
Sepals, petals, stamens, and pistils are the structures of this.
What is a flower
Those are the female reproductive parts of a flower.
What are pistils?
A plant's shoot system grows away from it.
What is gravity?
They produce food and cause photosynthesis.
What are leaves?
