They are organs that plant uses to create it’s most own nutrients.
Leaves
Plant nutrition consists of three processes: absorbing water and minerals, ___, and carrying out photosynthesis.
absorbing carbon dioxide
It occurs in response to physical contact. This phenomenon is evident in creepers or climbing plants which grow up around the objects with which they come into contact.
Thigmotropism
They are plants with seeds in a fruit.
Angiosperms
These are the tubes located inside the stems where the substances are distributed throughout the plant.
Vessels
It occurs in response to water. This occurs in roots, which tends to grow towards water in the soil.
Hydrotropism.
It produces the male gametes.
Stamens
It occurs in response to light. For example, the stems of plants grow towards the light.
Phototropism
Sexual reproduction is carried out via gametes. True or False?
True
When plant respire, they absorb oxygen which is used by their mitochondria to obtain energy from the carbohydrates produce there. True or False?
True
They are plants with seeds that are not in a fruit.
Gymnosperms
These are plant responses in which plants direct their growth towards or away from a stimulus.
Tropisms
It occurs in response to gravity. This is most evident in roots, which grow in the direction of gravitational pull (downwards).
Gravitropism
Plants are constantly respiring. True or False?
True
Respiration produces gas and a waste product, carbon dioxide. True or False?
False, it produces water.
It produces female gametes.
Pistil
They grow into the soil and their job is to absorb water and minerals.
Roots
It is the mixture of water and minerals absorbed through the roots.
Xylem sap
Carbon dioxide enters the plant mainly through tiny pores called ___.
Stomata
It contains the reproductive organs of the plant.
Flowers
Plants with seeds, are called ___.
Spermatophytes
They keep the plants erect and hold up the leaves.
Stem
Plants are ___ because they produce their food through photosynthesis.
autotrophic
Sexual reproduction in plants can be carried out through bud formation, fragmentation or spores. True or False?
False, asexual reproduction
Photosynthesis produces carbon dioxide as a waste product. True or False?
False, it produces oxygen.
