Task 4

Topic: General information about animals

The difference between animals and plants

signs Plants Animals
Nutrition Autotrophic (photosynthesis). Heterotrophs (dead organics – saprophytes, live – predators, parasites).
Cell structure There is a cellulose membrane, vacuoles. chloroplasts. There is no cell center (only in some unicellular). There is no shell, vacuoles (with the exception of food in protozoa), chloroplasts. has a cell center.
fabrics Educational. integumentary, conductive, mechanical, basic Epithelial, connective, muscular, nervous.
Organs Vegetative: root, shoot (stem, leaves, buds) Reproductive: flower, seed, fruit Somatic: organs of the musculoskeletal, circulatory, respiratory, nervous, digestive, excretory, integumentary, endocrine systems. Reproductive: organs of the reproductive system.
Spare substances Starch, proteins, fats. Fats, glycogen, proteins.
Ability to move in space Only flagellated unicellular organisms move. tropisms are characteristic of multicellular organisms (phototropism – movement towards light). Most animals are active
Ability to grow Throughout life For most animals only in youth.
activity in search of food Not active. Most of them are active.
Manifestation of irritability and excitability Manifestations in plants differ sharply from the usual forms of motor and nervous activity of animals. There are (irritability in everyone, higher nervous activity in more highly organized).

The organism of a multicellular animal differs from a plant

The body’s ability to

1) movement and growth

2) sexual reproduction

3) conduction of a nerve impulse

4) metabolism and energy

Animals, like plants,

1) take in carbon dioxide and give off oxygen

2) feed on ready-made organic substances

3) reproduce sexually and asexually

4) grow throughout life

Animals, unlike plants,

1) have a cellular structure

2) when breathing, they take in oxygen and give off carbon dioxide

3) feed on ready-made organic substances

4) reproduce sexually

4. Animals, like plants,

1) have a cellular structure

2) feed on ready-made organic substances

3) lead an active lifestyle

4) absorb carbon dioxide and release oxygen

An animal’s response to a particular stimulus is called

1) instinct

2) behavior

3) reflex

4) feeling

What system is necessarily present in the body of a multicellular animal

1) nervous

2) organs of movement

3) respiratory

4) digestive

The development of an animal is considered

1) changes in the functions of organs as they grow

2) changing the size of his body

3) exchange of matter and energy with the outside world

4) the ability to respond to external stimuli

Has a constant body temperature

1) Butterfly cabbage white

2) House spider

3) Domestic duck

4) Common snake

9. Does not have a constant body temperature

1) crocodile

2) house mouse

3) gray goose

4) domestic chicken

Task 5

Topic: Unicellular animals

The amoeba, as an inhabitant of fresh water bodies, is characterized by the presence of

1) pseudopods 3) contractile vacuole

2) flagella 4) digestive vacuole

2 . Of the listed protozoa, flagellar unicellular include

1) common amoeba

2) infusoria-shoe

3) green euglena

4) amoeba dysentery

What is the function of organelles containing chlorophyll in green euglena?
