Fill in the blank prokaryotes and_________ are two TYPES of cells

Explanation
Prokaryotes and eukaryotes are two types of cells. Prokaryotes are single-celled organisms that lack a nucleus and membrane-bound organelles, while eukaryotes are more complex organisms with a true nucleus and membrane-bound organelles. This classification is based on the structural differences between the two types of cells, with eukaryotes being more advanced and capable of performing more complex functions.

Animal and________are two kinds of cells

Explanation
The given statement suggests that "animal" and "plant" are two kinds of cells. This implies that the cells being referred to are specific to animals and plants, indicating that animal cells and plant cells are the two types of cells being compared. Therefore, the correct answer is "plant."

Which of the following is FALSE about eukaryotes?

A.

Many internal structures and membranes
B.

Fungi,protist,plants,animal
C.

No nucleus
D.

Larger, more complex
E.

All true

Correct Answer
C. No nucleus

Explanation
The given correct answer states that eukaryotes do not have a nucleus. This is false because eukaryotes are defined by the presence of a nucleus, which contains the genetic material. Eukaryotes are organisms that include fungi, protists, plants, and animals, and they are characterized by having many internal structures and membranes. They are also generally larger and more complex than prokaryotes, which lack a nucleus.

Kingdom________: -true bacteria -algae

Correct Answer
eubacteria

Explanation
The correct answer is eubacteria. Eubacteria is a kingdom that includes true bacteria, which are prokaryotic organisms that lack a nucleus and membrane-bound organelles. Algae, on the other hand, are classified in the kingdom Protista. Therefore, eubacteria is the correct answer as it is the kingdom that includes true bacteria.

Nucleus in the cell is the control center and where____is located(hint: less than 5 letters)

Correct Answer
DNA

Explanation
The nucleus in the cell is the control center and where DNA is located. DNA is a molecule that contains the genetic instructions for the development and functioning of all living organisms. It is stored in the nucleus of eukaryotic cells, which includes plants, animals, and fungi. The nucleus protects and regulates access to the DNA, allowing for the control and coordination of cellular activities.

Vacuole is the______, where water and food is stored. (hint: seven letters)

Correct Answer
storage

Explanation
The question is asking for a seven-letter word that describes the vacuole, where storage, water, and food are stored. The correct answer is "storage" as it fits the given criteria and accurately describes the function of the vacuole in cells. The vacuole acts as a storage compartment within the cell, storing various substances such as water, nutrients, and waste products.

Cytoskeleton -microtubule is made of______.

Correct Answer
tubulin

Explanation
Microtubules are one of the components of the cytoskeleton, which is a network of protein filaments that provide structural support and help maintain the shape of the cell. Microtubules are made up of tubulin, which is a protein that forms long, hollow cylinders. These cylinders provide a framework for cell division, as well as for the movement of organelles and other cellular components. Therefore, the correct answer is tubulin.

8.

Cytoskeleton -microfilaments is made of______.

Correct Answer
actin

Explanation
Microfilaments are one of the three main components of the cytoskeleton, along with microtubules and intermediate filaments. They are made up of actin proteins, which form long, thin fibers. These actin filaments provide structural support to the cell and are involved in various cellular processes such as cell movement, cytokinesis, and cell shape maintenance. Therefore, the correct answer to the question is actin.

Chloroplasts are organelles that capture the energy from sunlight and convert into chemical energy called____________.

Correct Answer
photosynthesis

Explanation
Chloroplasts are responsible for capturing energy from sunlight and converting it into chemical energy through a process called photosynthesis. During photosynthesis, chloroplasts use pigments such as chlorophyll to absorb light energy, which is then converted into chemical energy in the form of glucose. This process is essential for plants and some other organisms to produce food and oxygen.

Rough endoplamsic reticulum: __found on surface, and smooth ER has no_on surface. (only one word to fit in both blanks)

Correct Answer
ribosomes

Explanation
The rough endoplasmic reticulum is characterized by the presence of ribosomes on its surface, while the smooth endoplasmic reticulum lacks ribosomes on its surface. Ribosomes are responsible for protein synthesis, and their presence on the rough endoplasmic reticulum indicates that this organelle is involved in the production and processing of proteins. On the other hand, the smooth endoplasmic reticulum is involved in lipid metabolism and detoxification processes, which do not require the presence of ribosomes.

Lysosomes are small organelles filled with_________.

Correct Answer
enzymes

Explanation
Lysosomes are small organelles filled with enzymes. Enzymes are specialized proteins that catalyze chemical reactions in the cell. Lysosomes contain a variety of enzymes that help break down and digest cellular waste materials, foreign substances, and even damaged organelles. They play a crucial role in maintaining cell health and recycling cellular components.
