Question

Answer the following questions. 1. Leaves other than green colour perform photosynthesis. How will you test it? 2. Write steps to find out how silk is produced.Answer the following questions. ​

Answer 1

Answer:

Hypothesis C: 'Red leaves contain very small amount of chlorophyll as compared to red pigment. ... Red-coloured leaves of plants do not photosynthesise as they lack the green pigments (chlorophyll). 2. Parts of plants other than leaves that contain green pigments (chlorophyll), perform photosynthesis.

Hello ,

Here is your answer :-

It is a Chinese silk making process.

The silkworms and mulberry leaves are placed on trays.

Twig frames for the silkworms are prepared.

The cocoons are weighed.

The cocoons are soaked and the silk is wound on spools.

The silk is woven using a loom.

Hope my answer will be helpful !!!

Answer 2

1. Leaves other than green colour perform photosynthesis.

Explanation:

• Plants that are photosynthesizing have carbohydrates stored within them.
• An iodine test will demonstrate that leaves of colours other than green also contain stored carbohydrates.
• When starch is present, iodine changes colour to a blue-black hue.
• The leaf does not perform photosynthesis if, however, it does not turn blue-black when iodine is added.

2. Write steps to find out how silk is produced.

Steps:

1. Silk is made from silkworm cocoons.
2. Because silkworm eggs are the starting point for the silk production process, the female silk moth lays eggs.
3. The temperature of these eggs is then raised to one that will allow them to warm.
4. The silkworms produced from these eggs are given mulberry leaves to help them thrive when they hatch.
5. The silkworms stop consuming the leaves after a particular period of time and begin creating cocoons.
6. Once these cocoons are complete, the silkworms within are killed by keeping them under heat, and the silk strands are then retrieved.
