Vaifoa- Photosynthesis

Image result for photosynthesis
Greetings and welcome to my new blog post, within the five weeks at school in Science with Mr Tyagi, we've been learning about "Photosynthesis" If you don't know what the definition of photosynthesis is, it's right down below if you want to check it out :D Please leave some feedback in the comment section to help me improve or just a nice feedback, I'd really appreciate it. Thank you very much for visiting my blog.

Photosynthesis is a process in which green plants prepare their food in the presence of sunlight by taking carbon dioxide from the environment and water from the earth. Chlorophyll present in green leaves converts carbon dioxide and water to glucose and oxygen. This oxygen is used by all living organisms to survive.
Go to the website given below and read the text carefully so as to learn the process of photosynthesis in detail. Watch video and enjoy flashcards.

When finished answer the questions given below.

Give 3 examples of how plants support life.
  1. They provide food (cereals, fruits & vegetables)
  2. They provide oxygen which is necessary for life
  3. They provide medicines
  4. They provide habitat

What is Photosynthesis?
Photosynthesis is a process in which carbon dioxide and water are used by the plants to produce carbohydrate in the presence of su
Write word equation for photosynthesis:

  1. List the reasons why water is so important for the plants.
Water is very important for the plant because the plant needs the water as part of making it’s own food, getting in oxygen so it is able to grow. In photosynthesis, it is explained that water is used to be apart of the process of photosynthesis, plants need water for it to be able to grow and get oxygen.

  1. Describe how plants lose water to the atmosphere
Plants lose water to the atmosphere because the causes evaporation towards the water. So the sunlight turns the liquid water into gas particles that float within the sky and that is the process of evaporation to condensation which allows the particles in the sky to drop and turn into water. That entire process of evaporation to condensation is well known to be called “transpiration.”

What 4 ingredients are needed for plants to make their own food?
  1. Water
  2. Sunlight
  3. Carbon dioxide
  4. Chlorophyll

Extra Work:
Write down the names of plants which have adopted themselves for one or the other reasons like loss of water staring food etc.

Plants lose water from the process of the sun making it’s entrance, as it removes the water from the plants… this is called “evaporation”, which transforms the water into gases.

In your own words, describe what happens during photosynthesis:

Plants needs sunlight, water, carbon dioxide and chlorophyll to be able to make it’s own food, this process is called photosynthesis. During photosynthesis, water falls into the ground where the plants are and then that water goes into the roots of the plant.

  1. Hi Vifoa, it's so great to be able to see your learning from the other side of the world! You are very adept at using your own words to describe your new understanding of concepts. I have an extra question though! Why are the leaves on a cactus more like spines? And how does that link to water loss or photosynthesis?
