Question

Изучите таблицу простейшие.зарисуйтк схему строения амебы.подпишите названия частей её тела. какую роль в процессе жизнедеятельности они выполняют?

Answer 1

Рисовать не буду, но объясню.Тело амебы обтекаемое, т.е. оно может изменяться и никогда не бывает постоянной формы, присутствуют ложноножки, с помощью которых она двигается, сократительная вакуоль, с помощью которой выводится продукты обмена из организма, пищеварительная вакуоль, ядро.
Роли они выполняют разные, например: паразитизм(дизентерийная амеба), мутуализм (киш.амеба), редуценты

Answer 2

Ameba Structure and Function

An amoeba is a single-celled organism that belongs to the group of protozoans. It has a simple structure and performs essential functions for its survival.

Structure of an Amoeba: An amoeba has a simple structure consisting of the following parts: 1. Cell Membrane: The outer boundary of the amoeba, which separates the cell from its environment and controls the movement of substances in and out of the cell. 2. Cytoplasm: The jelly-like substance filling the cell and containing the organelles. 3. Nucleus: The central part of the cell that controls its activities and contains genetic material.

Functions of Each Part: - Cell Membrane: The cell membrane regulates the movement of substances in and out of the cell, maintaining the cell's internal environment and allowing it to interact with its surroundings. - Cytoplasm: The cytoplasm houses various organelles and is the site of many chemical reactions essential for the cell's survival. - Nucleus: The nucleus contains the genetic material of the cell and controls its activities, including growth, metabolism, and reproduction.

Schematic Representation: Here's a simple schematic representation of an amoeba's structure: ``` _______________________ | Cell Membrane | |______________________| | | | Cytoplasm | |______________________| | | | Nucleus | |______________________| ```

In this schematic representation, the cell membrane, cytoplasm, and nucleus are labeled to illustrate the basic structure of an amoeba.

Amoebas play a crucial role in the ecosystem as they are part of the microbial food web, consuming bacteria and other microorganisms, and serving as a food source for larger organisms. They also contribute to the decomposition of organic matter, playing a vital role in nutrient cycling in various environments.
