Thus, a concave mirror forms a virtual, erect and magnified image when the object is placed very close to the mirror. Explanation: When the object is between the focus and the pole (Very close to the mirror) of the mirror then a virtual, erect, and magnified image is formed.

It is translocation not transcolation

Harsh Pal 2 years, 1 month ago

Translocation is the movement of dissolved substances, such as sucrose and amino acids, from parts of the plant where the substances are made to other parts of the plant where they’re needed. Translocation takes place in the phloem - transport vessels made up of two types of cell, sieve tube elements and companion cells. The parts of the plant which make these substances are referred to as sources (e.g. the leaves) and the parts of the plant which store or use the substances are called sinks (examples include bulbs and roots). When sucrose reaches a sink, it is converted into starch for carbohydrate storage. This maintains a concentration gradient between the source and the sink, so that more sucrose moves into the source. Translocation is an active process, so if respiration is reduced or inhibited (e.g. using a respiratory toxin), translocation will be impaired. The Mass Flow Hypothesis The mass flow hypothesis is a theory which attempts to explain how solutes are transported from source cells into sinks through the phloem. It isn’t concrete, but it is the best-accepted theory we currently have based on the available evidence. It states that mass flow of solutes takes place in the phloem in the following stages: Sucrose moves from companion cells into sieve tube elements by active transport. This reduces the water potential of the sieve tube element. Water moves into the phloem by osmosis, which increases the hydrostatic pressure. There is a pressure gradient with high hydrostatic pressure near the source cell and lower hydrostatic pressure near the sink cells. Solutes move down the pressure gradient towards the sink end of the phloem. Solutes move into sink cells and are converted into other molecules (e.g. starch). The removal of solutes increases the water potential at the sink end, causing water to move out of the phloem by osmosis. This maintains the hydrostatic pressure gradient between the source and the sink

What are saprophytes????

Harsh Pal 2 years, 1 month ago

Saprotrophic microscopic fungi are sometimes called saprobes. Saprotrophic plants or bacterial flora are called saprophytes (sapro- 'rotten material' + -phyte 'plant'), although it is now believed[citation needed] that all plants previously thought to be saprotrophic are in fact parasites of microscopic fungi or other plants. The process is most often facilitated through the active transport of such materials through endocytosis within the internal mycelium and its constituent hyphae.[3] Mycelial cord made up of a collection of hyphae; an essential part in the process of saprotrophic nutrition, it is used for the intake of organic matter through its cell wall. The network of hyphae is referred to as a mycelium, which is fundamental to fungal nutrition. Various word roots relating to decayed matter (detritus, sapro-), eating and nutrition (-vore, -phage), and plants or life forms (-phyte, -obe) produce various terms, such as detritivore, detritophage, saprotroph, saprophyte, saprophage, and saprobe; their meanings overlap, although technical distinctions (based on physiologic mechanisms) narrow the senses. For example, usage distinctions can be made based on macroscopic swallowing of detritus (as an earthworm does) versus microscopic lysis of detritus (as a mushroom does).

Why can't we use a plain mirror as a side mirror in a scooter or a car

Posted by Dnyanada Singh 2 years, 1 month ago

CBSE > Class 07 > Science

2 answers

Harsh Pal 2 years ago

Hint: We all use convex mirrors in the side view of our cars, to see the image of any object's broader field of view that makes us comfortable while driving. Whereas a plane mirror will show the image bigger that makes it uncomfortable while driving. Complete answer: A convex mirror is used instead of a plane mirror because it has a large view angle with always an erect image formation irrespective of the position of the object.Convex mirrors are preferred as rear-view mirrors in vehicles because they provide a broader field of view, allowing the driver to see the majority of the traffic behind him. In cars and vehicles, a convex mirror is favoured as a rear-view mirror because it provides a broader field of view, allowing the driver to see the majority of the traffic behind him. Convex mirrors always reflect the objects in front of them in an erect, imaginary, and shrunken form. Convex mirrors always reflect the items in front of them in a virtual, erect, and shrunken picture. -A virtual picture is always formed by a convex mirror and is always situated behind the mirror. -The picture is vertical and located at the focal point when the item is far away from the mirror. -As the object approaches the mirror, the image follows suit and increases until it reaches the same height as the object. -Convex mirrors produce images that are smaller than the item but become larger as they approach the mirror. Therefore, a convex mirror is used instead of a plane mirror in the side view of a car because the image formed by a convex mirror is smaller and closer to that formed by a plane mirror. Hence, the correct options are (B) and (C). Note: As long as the object is in their focus, concave mirrors in vehicles help to reduce blind spots. The reflecting surface of a concave mirror, on the other hand, bends inwards and away from the light source.
