So, the Sun's light takes about 8.3 minutes to reach us. This means that we always see the Sun as it was about 8.3 minutes ago. ... The nearest large galaxy to us, Andromeda, is 2.5 million light-years away. So, we see Andromeda as it was 2.5 million years in the past.
<h2>Permanent tissues in Plant</h2>
Explanation:
A) The cell walls of parenchyma cells are thinner than those of sclerenchyma cells
Plants posses basically two kinds of tissue- meristematic tissue and permanent tissue.
Meristematic tissue is made up of cells which are capable of active division and give rise to other tissues,.
Permanent tissue are already differentiated and usually do not divide.
Permanent tissues are -collenchyma, sclerenchyma and parenchyma.
Parenchyma and collenchyma are living whereas sclerenchyma is non-living.
