In the process of photosynthesis, plants have three main parts:

roots, stems, and leaves

Living organisms are classified into five kingdoms. To classify living organisms into kingdoms, several criteria have been taken into account, such as: if they are unicellular or multicellular; whether their cells have a nucleus, and whether their nutrition is autotrophic or heterotrophic.

Algae and protozoa belong to the protist kingdom

true

Bacteria are protozoa

false

Protists can be unicellular or multicellular

true

Amoebae belong to the monera kingdom

false (protista)

Some protists manufacture their own food

true

Protozoa are microscopic creatures

true

funghi

eukaryotic cells, feed other living things (heterotrophs), some are beneficial and some are harmful

bacteria

prokaryotic cells, feed other living things (heterotrophs), can move, can only be seen through a microscope, some are beneficial and some are harmful

cyanobacteria

prokaryotic cells, make their own food (autotrophs), can only be seen through a microscope

protozoa

eukaryotic cells, feed other living things (heterotrophs), can move, can only be seen through a microscope

algae

eukaryotic cells, make their own food (autotrophs), feed other living things (heterotrophs), can move

What are characteristics of the protist kingdom?

a. They can manufacture their own food.

b. They live in water, and have beautiful and varied colors.

c. They can reproduce sexually or asexually.

d. They do not have organs: roots, stems and leaves.

e. They do not cause diseases.

Bacteria

They can live in the bodies of different living organisms, and can also cause the destruction of living plants or animals

Protozoa

Heterotrophic creatures, made up of single cells, such as amoeba and paramecium

Algae

They are unicellular or multicellular creatures that live in aquatic or very humid environments

Animal kingdom

It is the most evolved and is divided into two large groups: vertebrates and invertebrates, They are organisms with eukaryotic cells. They are cellular, form tissues and, almost always, organs, apparatuses and systems. It has heterotrophic nutrition

Plant kingdom

They produce their food through photosynthesis, Eukaryotic cells are organisms with rigid walls and chloroplasts. They are cellular, with tissues and, almost always, organs. Their nutrition is autotrophic

Funghi kingdom

This name is used to designate the kingdom of fungi

Monera kingdom

This group is found in all habitats and is made up of single-celled organisms without a specific nucleus

Protoctis kingdom

It includes eukaryotic organisms that are not considered animals, plants and fungi, They are single-celled and prokaryotic organisms. Their nutrition can be autotrophic and heterotrophic. Sometimes they form colonies

Name the living organisms that have cells with nuclei, do not form tissues, are heterotrophic and are unicellular

prokaryotes

Name the kingdoms that contain autotrophic living organisms

monera, protists, plants

Name the kingdom that contains unicellular, multicellular and microscopic organisms

protists

pistil

The female part of the flower

stambrea

The male part of the flower that consists of the anthers and filaments

petal

Each of the colored leaves that make up the corolla and surround the flower

sepal

Each of the green leaves that make up the calyx of the flower

pollen

The male cells produced in the stamen of the flower

peduncul

The stem that joins the flower to the plant

filament

The long part that connects the anther to the calyx of the flower

anther

Part of the stamen of the flowers. It is a small sac, simple or double, in which pollen is produced and stored

Where do bacteria live?

Most bacteria live on land or in water, but many live inside or on the surface of other organisms, including humans. Bacteria can be found everywhere, because they are very resistant and adaptable microorganisms, and can survive in a wide range of environments. In addition, bacteria are transported by air, water, food and living organisms, which increases their ability to disperse.

What is the difference between a fungus and an algae?

Fungi can be multicellular; algae are always unicellular.

Fungi are heterotrophic; algae are autotrophic.

There are pathogenic species of fungi, but not algae.

How do flowering angiosperms differ from gymnosperms?

Gymnosperms: Trees and shrubs, most of which are evergreen, do not produce fruit, and their seeds are produced in cones.

 

Angiosperms: The most numerous group of plants; Trees and shrubs and grasses; They are the majority of the plants we use for food; They produce flowers, some of which are very small, and produce seeds inside fruits.
