Plant nutrition (photosynthesis)
****The water and minerals are absorbed by the ROOTS (raw sap)
***solar energy and carbon dioxide are absorbed by the leaves
What is plant respiration?
The process of plants breathing - They absorb oxygen from the air.
sexual plant reproduction is a process in which plants reproduce with WHAT?
sexual plant reproduction is a process in which plants reproduce with .... SEEDS!
Asexual plant reproduction occurs when plants reproduce WITH OR WITHOUT seeds?
Photosynthesis
What part of the plant transports the plant's food to all the parts of a plant?
The STEMS (which transport the elaborated sap)
TRUE OR FALSE: Plant respiration occurs during the DAY AND NIGHT.
TRUE!
ANGIOSPERMS OR GYMNOSPERMS:
Reproduce by developing seeds inside FRUIT.
Angiosperms
TRUE OR FALSE:
Asexual plant reproduction happens in ALL NON-FLOWERING plants and in SOME species of flowering plants.
TRUE
In photosynthesis: What part of the plant absorbs water and minerals (raw sap) from the soil?
Raw sap is absorbed by the roots at the BEGINNING of photosynthesis, it is a mixture of WATER & MINERALS from the soil.
Elaborated sap is the plant's food, that is created at the END of photosynthesis, when solar energy combines carbon dioxide with the raw sap. Elaborated sap is MOSTLY SUGAR.
ANGIOSPERMS OR GYMNOSPERMS:
Reproduce by developing seeds inside CONES.
Non flowering plants, such as mosses and ferns, reproduce using WHAT?
SPORES
What are plants that reproduce with seeds called?
FLOWERING PLANTS (they undergo sexual reproduction)
Why is photosynthesis such an important process and how does it benefit the earth?
Photosynthesis is important because all humans and animals need plants to survive. The process creates oxygen for the atmosphere, which we need to breathe. This is how plants sustain life on the planet.
During the daytime, plants do RESPIRATION AND PHOTOSYNTHESIS. But they release LESS oxygen than they need.
Plants do respiration and photosynthesis in the daytime, but they release MORE oxygen than they need.
This is how plants sustain life on the planet.
ANGIOSPERMS VS. GYMNOSPERMS:
In this plant, pollination occurs when ANIMALS OR WIND transfer POLLEN from the anther into the stigma.
ANGIOSPERMS
Spores are protected inside of cells called ___________?
BONUS POINTS: WHAT HAPPENS WHEN THE CAPSULES OPEN??
Spore capsules
When the capsules open, the wind BLOWS the spores off of the plants -- A new spore can grow when a spore falls on the ground!
Elaborated sap (it is made after the chlorophyll absorbs solar energy, mixing the raw sap with carbon dioxide to produce elaborated sap)
What is chlorophyll, and why is it important in the process of photosynthesis?
Chlorophyll is a green substance in the leaves that collects solar energy.
It is important to photosynthesis because the energy it absorbs is used to combine RAW SAP with CARBON DIOXIDE to make the plant's food. The plant's food is called ELABORATED SAP.
How is respiration different from photosynthesis? Explain.
In respiration, the plant takes IN Oxygen & lets OUT Carbon dioxide.
In photosynthesis, the plant takes IN carbon dioxide, solar energy, nutrients and water, and transforms them into FOOD, letting OUT oxygen.
Photosynthesis only occurs in the DAYTIME, and Respiration occurs during the DAY & NIGHT.
ANGIOSPERMS OR GYMNOSPERMS:
WHERE does each plant produce the pollen and ovules?
ANGIOSPERMS:
-The ANTHER produces pollen
-Animals transfer pollen into the STIGMA (pollination)
-The pollen moves down the STYLE into the OVARY, where the ovules are.
GYMNOSPERMS:
-Pollen is produced on the MALE CONES.
-Wind blows the pollen to the female cones (pollination)
-Ovules are in the FEMALE CONES. (They join and it is fertilisation)
When its stolons touch the ground, new roots and a new plant grow in that spot!
STRAWBERRY PLANT
In sexual plant reproduction:
What is the process of pollen joining with the ovule called?
