17:You are looking at some prepared slides of different types of
animal tissue. Unfortunately, the labels are so old that they have
faded to the point where you can no longer read them. All of these
slides show tissue that form a long row with tight connections
between the cells. These slides are showing examples of which type
of tissue?
A:Muscle tissue.
B:Dermal tissue.
C:Epithelial tissue.
D:Connective tissue.
18:Which of the following is the best description of the difference
between physiology and anatomy?
A:Anatomy focuses on homeostasis; physiology focuses on the
detailed functions required to maintain
homeostasis.
B:Anatomy focuses on the cellular and tissue levels of
organization; physiology focuses on the organ, organ system, and
organism levels.
C:Physiology focuses on the structure of an organism; anatomy
focuses on the functions.
D:Anatomy focuses on the structures of an organism; physiology
focuses on the functions.
19:Which of the following statements about plant tissue and organs
is incorrect?
A:The properties of water are vital to transport through
phloem.
B:Dermal tissue performs a function that is similar to breathing in
animals.
C:Ground tissue in roots and leaves perform different
functions.
D:the majority of photosynthesis occurs in ground tissue.
Ans.1
Let us go through the the structure of each of the tissue's mentioned in the answer option's and find out which one of them form a long row with tight connections between the cells and hence the answer.
(a) Muscle tissue - These are soft tissue's that forms the muscules in animals and also gives it the ability to contract.They are made up of fibers of muscle cells that are connected together in sheets and fibers known as the muscles.
(b) Dermal tissue -These are tissue found in plants that protects their soft tissues and also controls their interation with surroundings and called as epidermis.They are thick single layer of cells that cover the plant parts.
(c) Epithelial tissue.- These are tissues that provides protection from physical,chemical and biological impact to the body at the intermediate level.They are scutoid in shape and are tightly packed,forming a continous sheet with no intercellular spaces.Adjacent epithelial cells are sealed by tight junctions,into a narrow band.
Hence, the answer is (C) Epithelial Tissue.
