    The photoperiodic stimulus is picked up only by the leaves in plants. For this purpose, leaf is of utmost importance. For the perception of photoperiodic cycle, presence of leaves under inductive photoperiod is essential, so that, the hormone required for flowering can be produced. Therefore, in the absence of leaves, i.e, in a defoliated plant light perception would not occur, i.e., the plant would not respond to light.

    Metamerism is a body type exhibited by members of the phylum Annelida. It means that the body is composed of repeating segments attached to make a whole. These segments are known as metameres, and the lines we see externally separating each segment are called annuli. Metamerism is easily visible in earthworms.

    Micturition is the process of expulsion of the final selectively secreted and processed filtrate (commonly known as Urine) from the body through the Urethra. Before micturition, urine is held in an elastic muscular bag like structure called urinary bladder connecting the ureters from kidneys to the urethra. They contain stretch receptors that are in turn associated with certain osmoregulatory regions in the brain. When the urinary bladder is filled with urine, stretch receptors send signals to brain that urine must be expelled so as to accommodate the urine that is coming from kidneys (Urine production is a continuous process). Thus, the brain signals the urethral and bladder muscles to help the bladder remove the urine stored (about 1-1.5 L a day).

    Prokaryotic cells have not well developed organelle other than ribosome while eukaryotic have well developed organelle including ribosome,nucleus,nuclear membrane etc

    4Thank You

    Anjan Karthi 1 year, 2 months ago

    A prokaryotic cells represent the earlier forms of life that existed on earth and they have no distinct cell nucleus or membranes bound cell organelles. They have a severely indistinct nucleoid region of condensed chromatin network and smaller 70S ribosomes (with 30S and 50S subunits) with special bodies replacing cell organelles such as the inclusion bodies, chromatophores and mesosomes. On the other hand, eukaryotic cells have a much more complex organization with proper membrane-bound cell organelles and larger 80S ribosomes (with 40S and 60S subunits).

    Ventricles usually have very thick walls so that they can withstand the pressure with which they have to pump blood so that blood circulates through each and every tissue of the body. But, left ventricle is the one that actually sends the blood to most body tissues, so the LV is the thickest due to which aorta has to withstand higher pressure. But, RV does not need that much pressure or thickness as it has to pump blood only to the lungs. So, the pulmonary artery also experiences relatively lower pressure than aorta. So, considering (1), thicker the ventricular wall, more would be the pressure it's associated artery has to withstand. Considering (2), more the number of tissues to which blood must reach and more the distance the blood must travel to reach tissues, greater will be the pressure on the great arteries. (GREAT ARTERIES IS THE COLLECTIVE TERM FOR AORTA AND PULMONARY ARTERY)

    How do the roots of the plants growing in swamps and marshes obtain their oxygen? A.1. The roots of the plants growing in swamps and marshes grow vertically upwards and respire. They become negatively geotropic. Q.2. Name some modifications of plant parts for the purpose of photosynthesis. A.2. The stem gets modified into a leaf-like structure to carry out photosynthesis. In plants like Trapa and Tinospora, the roots grow out of the soil and develop chlorophyll to perform photosynthesis. Q.3. What are the edible parts of ginger and onion? A.3. The modified stem is the edible part of ginger. All the food material is stored here. The fleshy leaves of onion are the edible parts. Q.4. Differentiate between pinnately compound leaf and palmately compound leaf? A.4. Pinnately Compound LeafPalmately Compound LeafThe midrib of the leaves is present on a common axis called the rachis.Leaflets are attached at the tip of the petiole. Q.5. Explain different types of phyllotaxy with suitable examples. A.5. The pattern in which the leaves are arranged on the stem is known as phyllotaxy. These are of three types: Alternate Phyllotaxy- The leaf arises from each node in an alternate manner. For eg., China rose, sunflower. Opposite Phyllotaxy- The leaves arising at each node lie opposite to each other. For eg., Calotropis Whorled Phyllotaxy– More than two leaves arise at each node and form a whorl. For eg., Alstonia Q.6. Describe the modifications of the stem. Give examples for the same. A.6. Modifications of the stem are as follows: Stem Tendrils- These may be branched with scaly leaves. Eg., Passiflora, Antogonon Stem Thorns- These are sharp needle-like structures that are formed to reduce transpiration and also act as a defence. For eg., Citrus, Pomegranate Phylloclades- These are green, flattened, succulent, leaf-shaped structures that perform photosynthesis. They possess indefinite growth. For eg., Opuntia, Euphorbia soyleana. Cladodes- They are green, photosynthetic of limited growth. The leaves are either modified into spines or reduced to scales. For eg., Ruscus, Asparagus Q.7. Which two roots develop from different parts of the angiosperm plant other than the radicle? A.7. Prop roots of the banyan tree- Develop from lower nodes of the stem of the tree Stilt roots in sugarcane- Arise from lower nodes of the stem and penetrate the soil. Both the roots are meant to provide support.
