Answers
Answer:
1- Plants exchange gases through tiny openings in the leaves called stomata.
2- A living thing that is able to feed itself using simple chemical substances such as carbon dioxide.
3- Oxygen and Glucose
4- Chlorophyll
5- A very small grey or yellow plant that spreads over the surface of rocks, walls and trees and does not have any flowers.
6- The food that you eat and the way that it affects your health.
7- Yes, birds are autotrophs, because they make their own food.
8- A heterotroph is an organism that cannot manufacture its own food by carbon fixation and therefore derives its intake of nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are secondary and tertiary consumers.
9- Rhizopus (bread mould), Mucor (pin mould), Yeast, Agaricus (mushroom) .
10- Some plants have deep red, violet or brown leaves. ... They are not like green plants as they lack chlorophyll and cannot make food by photosynthesis.
11- Carbon dioxide is the gas produced during photosynthesis.
12- Viscum and Loranthus are common examples of partial stem parasites.
13- Autotrophs and heterotrophs are the two classifications of organisms on the basis of nutrition. Autotrophs are organisms that can prepare their own food. On the contrary, heterotrophs depend on autotrophs and other organisms for nutrition.
14- Write the complete balanced reaction for Photosynthesis both in symbol and word equation. Carbon dioxide + Water → Glucose + oxygen. 6CO2 + 6H2O → C6H12O6 + 6O2.
