They are also called as microbodies
A
Microvilli
B
Lysosomes
C
Peroxisomes
D
Ribosomes
Explanation: 

Detailed explanation-1: -Peroxisomes are microbodies that are known to contain cata-lase and at least one flavin oxidase; glyoxysomes are micro-bodies that contain, in addition, isocitrate lyase and/or malate synthetase, two enzymes of the glyoxylate cycle.

Detailed explanation-2: -Peroxisomes, also called microbodies, are small, spherical organelles with a diameter of 0.5–1.5 µm (Fig. 1.16), which, in contrast to plastids and mitochondria, are enclosed by only a single membrane.

Detailed explanation-3: -A peroxisome, like other particles in the cell, is classified as a microbody. It is generally spherical and is bounded by a single membrane with a diameter of 0.1–1 µm (Fig. 2.21).

Detailed explanation-4: -This occurs via a series of reactions termed the glyoxylate cycle, which is a variant of the citric acid cycle (Figure 10.27). The peroxisomes in which this takes place are sometimes called glyoxysomes.
