Question

Answer

Cuscutta have a parasitic relationship with the host .So to get nutrients it harms the host

Answer

Which of the following is a parasite?
The correct answer is b) Cuscuta.
Cuscuta
(also known as dodder) is a parasitic plant that lacks chlorophyll and obtains its nutrients by attaching itself to other plants and absorbing their sap.
Algae
are photosynthetic organisms that produce their own food.
Mushrooms
and Yeast are types of fungi that are primarily decomposers or saprophytes, meaning they obtain nutrients from dead organic matter, not by parasitizing living organisms.

Answer

Function of Chlorophyll in Photosynthesis:

1. Capturing Solar Energy:
Chlorophyll is a green pigment found in the chloroplasts of plant cells. Its primary function in photosynthesis is to capture solar energy from sunlight. This process is called the light-dependent reaction, where chlorophyll absorbs light energy and converts it into chemical energy.

2. Absorption of Light:
Chlorophyll molecules contain a porphyrin ring structure that enables them to absorb light of specific wavelengths, mainly blue and red light. This absorbed light energy is used to power the photosynthetic process and convert carbon dioxide and water into glucose and oxygen.

3. Energy Transfer:
Once chlorophyll captures light energy, it transfers this energy to other molecules in the chloroplast, such as the reaction center of photosystem I and II. These molecules further use this energy to drive the synthesis of ATP and NADPH, which are essential for the Calvin cycle, the second phase of photosynthesis.

4. Essential for Photosynthesis:
Without chlorophyll, plants would not be able to capture sunlight and convert it into chemical energy. This pigment plays a crucial role in the overall process of photosynthesis, allowing plants to produce their own food and release oxygen as a byproduct.
In conclusion, chlorophyll's primary function in photosynthesis is to capture solar energy, which is essential for driving the chemical reactions that enable plants to convert carbon dioxide and water into glucose and oxygen.

Answer

B) cuscuta
It is a parasite because it lives in/on an organising that obtains nutrients from it .They can be plants or animals.

Answer

Chlorophyll's main role is to absorb sunlight or solar energy . Chlorophyll is the only substance of earth which can absorb sunlight , thus also called miracle substance

Answer

Option b is correct as algae is symbiotic, mushroom is decomposer , while yeast is saprophyte .cuscuta has haustoria so it is parasitic
