Plant Reproduction 1
What is the transfer of pollen into the stigma by animals or wind?
pollination
How do non flowering plants (mosses and ferns) reproduce?
using spores
What is the process of plants making their own food?
photosynthesis
Are plants producers or consumers?
producers
What are the two types of flowering plants?
angiosperms and gymnosperms
What protects the spore cell?
spore capsules
What takes the elaborated sap to all the other parts of the plant?
stems
What is the process when plants breathe?
Respiration
What are the parts of the female organ or pistil?
stigma, style and ovary
What are the parts of the male organ or stamen?
filament and anther
What is the difference of raw sap and elaborated sap?
raw sap is the mixture of roots absorb water and minerals from the soil. While elaborated sap is when raw sap combines with carbon dioxide to make food.
What is chlorophyll? What does it collect?
The leaves contain a green substance called cholorophyll, and it collects solar energy.
How to gymnosperms reproduce?
Wind blows pollen from the male cones into the female cones called pollination. Pollen joins the ovules inside the female cones and fertilisation occurs. Seeds begin to develop. The cone opens when it is mature. Seeds fall to the ground where they can grow into new plants.
Give me 3 examples of plants that asexually reproduce.
mosses, ferns, strawberry, potato
What is the first step of photosynthesis?
Fill in the blanks: The ______ absorb _____ and _____ from the soil. This is mixture is called _____.
The roots absorb water and minerals from the soil. This mixture is called raw sap.
Why is photosynthesis such an important process? How does it benefit life on Earth? Everyone in group should give me one sentence.
(own answers)
How do angiosperms reproduce?
The anther produces pollen. Animals or wind transfer the pollen into the stigma called pollination. The pollen goes down the style and into the ovary, where it joins the ovules called fertilisation. Seeds begin to develop. The ovary grows into a fruit with the seeds inside it. The fruit falls off. Later, it opens on the ground where the seeds can grow into new plants
What are the two kinds of asexual flowering plants? What are there differences?
Tubers and stolons. Tubers have underground stems. New roots grow from the tubers and produce new plants which are identical to the parent. Stolons have horizontal stems which grow above ground. When a stolon contacts the ground, new roots grow in that spot and a new plant begins to develop.
What is the third step in photosynthesis?
The leaves contain a green substance called chlorophyll. It collects solar energy. Using this energy, the raw sap combines with carbon dioxide from the air to make food. This food is called elaborated sap and contains mostly sugar. During this process, the plant releases oxygen into the air.
What happens in respiration? What happens during the day and the night?
They absorb oxygen from the air and expel carbon dioxide as waste. This happens during the day and at night. However, in the daytime during photosynthesis, they release more oxygen than they need.
