what is sactorial mouth where it is present |
| Answer» Leeches are ectoparasites and they mostly live on the blood of vertebrate animals, like - humans, cattle, etc. They have a sanguivorous i.e. blood-sucking feeding habit. The blood-sucking habit of Leeches is supported by a special adaptation in their mouth.Their mouth is a narrow triradiate aperture that sits at the center of the pre-oral chamber of the oral sucker. The oral sucker (or anterior sucker) is a tiny hollow muscular organ present at the anterior end of the animal body.\xa0The pre-oral chamber is actually a cup-like depression at the ventral surface of the oral sucker. One ray of the mouth is in medio-dorsal position, while the other two are placed ventro-laterally.\xa0This specially modified mouth of the Leeches is called suctorial mouth. When a feeding leech firmly adheres to the host body, its suctorial mouth moves like a saw and makes a triradiate (i.e. Y-shaped) painless incision in the victim\'s skin. Then the oozing blood of the host is sucked by the Leech. | |

Some fungi are parasites on living organisms, but most are\xa0saprophytes.\xa0Mushrooms\xa0contain no chlorophyll and most are considered\xa0saprophytes. That is, they obtain their nutrition from metabolizing non living organic matter. This means they break down and "eat" dead plants, like your compost pile does. | |

Mention the appendages involved in the locomotion of a typical annelid |
| Answer» All\xa0annelids\xa0except leeches also\xa0have\xa0chitonous hair-like structures, called setae, projecting from their cuticle.

|
Answer» he heart is roughly cone shaped hollow organ. It is approximately the size of owner’s closed fist and weighs about 250-300 gm in female and 300-350gm in the male. The heart lies in the thoracic cavity in the space between the lungs (mediastinum) anterior to the vertebral column and posterior to the sternum. The heart consists of 4 chambers. At first, the heart is divided into the right and left side by the septum. Each side is further divided into 2 chambers each by the atrioventricular valve. The upper two chambers are called atrium and lower two are called ventricles.

Motile cells are biflagellated but the two flagella are an equal im |
| Answer» A\xa0flagellum\xa0(/fləˈdʒɛləm/; plural:\xa0flagella) is a lash-like appendage that protrudes from the\xa0cell\xa0body of certain bacteria and eukaryotic\xa0cells\xa0termed as flagellates. A flagellate can have one or several\xa0flagella.\xa0Flagella\xa0are key structures concerned\xa0with bacterial motility. Nevertheless,\xa0bacteria\xa0that lack\xa0flagella\xa0may still be\xa0motile. A type of gliding\xa0motility\xa0can be achieved by the flexible movement of the whole cell. This is mainly observed on solid media, whereas flagellar motion is common to liquid environments.\xa0The primary purpose of\xa0cilia\xa0in mammalian cells is to move fluid, mucous, or cells over their surface.\xa0Cilia\xa0and\xa0flagella\xa0have the same internal structure. The major difference is in their length.\xa0Cilia\xa0and\xa0flagella\xa0move because of the interactions of a set of microtubules inside. | |

Multicellular organisms have division of labour . Explain . |
| Answer» Multicellular organisms are made up of millions and trillions of cells. All these cells perform specific functions. All the cells specialised for performing similar functions are grouped together as tissues in the body. Hence, a particular function is carried out by a group of cells at a definite place in the body. Similarly, different functions are carried out by different groups of cells in an organism and this is known as division of labour in multicellular organisms. | |
