THALLUS ORGANIZATION IN FUNGI ~ Fab Study

Image
Thallus organization in fungi Basically, thallus are divided in to two types. 1. Unicellular 2. Multicellular 1. Unicellular thallus:-   Unicellular organization occur in  some fungal groups. The most widely known are the yeast. Unicellular organization can be found in several fungi with motile zoospores in their life cycles. In Kingdom Fungi only the chytrids have both sexual and asexual motile flagellar cell which are generally posterior whiplash opisthokonts. Source Wikipedia 2. Multicellular thallus:-  Multicellular  fungi reproduce by making spores. Mold is a multicellular fungus. It consists of filaments called hyphae that can bunch together in to structure called mycelia. Source Wikipedia Hypha- Fungus body made of tiny filaments called hyphae. The group of hyphae is called mycelium. Hyphae are three types. 1. Uninucleate 2. Binucleate 3. Multinucleate Septa- Septa are two types. 1. Simplepore- Ex- Ascomycotina Source Wikipedia 2.D

NODAL ANATOMY ~ Fab Study

Image
What is Nodal Anatomy? It is the branch of botany which deals with internal structure and organization of plant or the plant organs are called plant anatomy. N.Grew (1641-1712)  is known as father of plant anatomy. K.A Chaudhary  is the father of indian plant anatomy. Anatomy of Nodal and internodal region are different:- The stem of plant is differentiated into nodes and internodes. The anatomical features of internodal region are is quiet different from that of the internodal region. This anatomical difference is due to the prescence of vascular supply to the leaves and branches from the main vascular cylinder of the stem. Nodal region of higher plants posses leaf gaps & leaf traces:- Each leaf that originates from the node, of higher plants possess vascular tissue of the leaves are connected to that of the stem. A vascular strand that extends between the vascular cylinder of stem and the leaf is called leaf trace or foliar trace. Even if the trace possess both xylem and phloem

Food chain and food web

FOOD CHAIN The transfer of food energy from the producers through a series of organisms with repeated eating and being eaten, is known as food chain. The solar energy is traped in the ecosystem by the green plants and produce energy rich carbohydrates. These green plants are known as primary producers. The green plants are eaten by plant eaters also called primary consumers. Herbivores  are in turn eater by meat eaters also called secondary consumers. Secondary consumers in turn may be still eaten by other carnivores which are known as tertiary consumers. After decay of both plants and animals simpler compounds are being released into the atmosphere due to the activity of deco posers which are re utilized by green plants. In nature we generally distinguish two types of food chain  ----- Gazing food chain and detritus food chain. Example-  A food chain in grassland ecosystem starts with grass and goes through grasshopper , the frogs , the snake and finally the Hawks.
